Enhance Engine
Performance &
Fuel Efficiency

“I would really recommend them to you as they are very honest people doing the business.. My toyota sienta was consuming alot of fuel about 13.5km/l despite doing the routine maintenance.. After doing stage 6, immediately, my car was feeling more responsive and light, so i was expecting a save on the fuel consumption. However, up to 6th tank, i noticed there was no changes in fuel consumption, despite on the huge difference in power delivery. I pm them, and they requested me to do a catalytic converter clean for my car, in which i did. Just after only 1 trip, the car was consuming at only 18.6km/l !! ..very huge difference! It was very smoooth like butter! I will definitely come back for more! Now.. driving is soo fun and really enjoyable !! thank you!!”

“Hey bro, a quick one-month update. The car continues to deliver a very pleasant and enjoyable driving experience. Gear changes remain smooth, idling vibrations are minimal, and the overall drive feels solid and reliable, which definitely inspires greater confidence behind the wheel. Power delivery is also well-judged, coming in smoothly and effortlessly when overtaking is needed. The biggest surprise, is the fuel efficiency — 7.4L/100km (13.1km/L). I genuinely never expected this from a 1.6-tonne executive sedan with a turbocharged petrol engine (non-hybrid). Previously, I was averaging around 13.1L/100km. Thank you, Gewinnen.”

“How is it that my average fuel consumption (Toyota Noah 1.8 R90 Hybrid) as shown on my odometer after installing Gewinnen products dropped from 18.7km/l to 18.1km/l but I am getting more mileage per full tank jumping from 850km to 950km and more? This looks contradictory at first, but it actually makes sense once you understand how the car calculates fuel consumption versus how real-world range works. Short Answer By ChatGPT / META Your odometer’s average fuel consumption (km/l) is an estimated, behaviour-weighted number, while distance per full tank is a real, physical outcome. After installing the Gewinnen products, your engine efficiency and usable fuel delivery improved, but the dashboard calculation hasn’t fully reflected that yet and in some cases, it never perfectly will. ⸻ So why the numbers don’t line up 1. The trip computer is an estimate, not a fuel meter Your car does not measure fuel burned directly. It estimates consumption using: • Injector pulse width • Engine load • Throttle input • Short-term driving patterns After installing Gewinnen parts (better airflow, smoother combustion, reduced drag), those assumptions can become slightly off. So: • The displayed km/l drops • But actual fuel usage improves This is very common after intake, exhaust, or friction-reducing upgrades. So Gewinnen product works. ⸻ 2. Driving behaviour changed without you realising With better response and torque: • You accelerate more smoothly • Less throttle is needed to maintain speed • Gear changes happen earlier • Engine spends more time in efficient RPM ranges But the trip computer may still “penalise” brief accelerations even though they burn less total fuel. Result: • Lower average km/l shown • Higher total distance travelled ⸻ 3. Average km/l is time-weighted, not distance-weighted If your recent driving includes: • More short trips • Cold starts • Traffic crawling The km/l average drops quickly. But over a full tank, your long steady cruising (where Gewinnen products shine) dominates. Tank range improves even though the displayed average worsens. ⸻ 4. You’re extracting more usable fuel from the tank Two subtle effects often happen: • More complete combustion • Slightly leaner, cleaner burn under light load That doesn’t always show up as better km/l, but it extends usable range before the low-fuel threshold. 850 km → 950+ km is a real-world efficiency gain, not imagination. MY FINAL VERDICT IS THAT THE SILLY LOOKING STICKERS ALL OVER THE ENGINE BAY REALLY WORKS! UNBELIEVABLE! AND I DON’T GET PAID TO WRITE THIS NOR AM I RECEIVING ANY FAVOURS AFTER THIS. 🤨”

“100% recommended for anyone to feel immediate power difference! No need to doubt, take a leap of faith and book right away”

“★★★★★ Transformed My Ride & Gave Me Peace of Mind! ​I'm absolutely blown away by the results after using Gewinnen! My car had been feeling sluggish always, almost like it was struggling to keep up, and I was starting to dread my daily commute. I'd read good things about Gewinnen, so I decided to give it a try, and I am so glad I did! ​From the moment I started driving after Leonard & Lionel installed it, the difference was night and day. My car feels significantly more responsive and powerful. Acceleration is smoother, and it tackles inclines with an ease it hasn't had in ages. It's like my car has found its second wind! ​But what truly sets Gewinnen apart isn't just the immediate performance boost, it's the incredible expertise and care they showed regarding my car's overall health. Not only did they deliver on the performance promise but they also took the time to explain exactly what was contributing to my engine's condition and, more importantly, provided invaluable advice on how to improve its longevity and efficiency. They shared specific tips on what type of engine oil to use and changing spark plugs every 40k etc that I had no idea about. This proactive approach to engine care is something I truly appreciate. ​It's clear that this product isn't just about a quick fix, they genuinely care about helping you maintain your vehicle in the long run. The combination of a noticeable performance improvement and expert guidance on engine maintenance makes this product/service an absolute game-changer. ​If your car is feeling a bit tired and you want to give it a new lease on life while also getting expert advice on how to keep it running smoothly for years to come, look no further than Gewinnen. It's a 5-star experience, hands down!”

“Was skeptical when I first saw it in FB. But I decided to take the leap of faith to try and install this. Got to say this has to be the best decision ever. The Nano Bros (Lionel & Leonard) are both skillful in this area and have extensive knowledge on cars itself. They are not just skilled, they are very helpful and willing to share their knowledge with car owners who may not know outside of P,R,N,D. Haha. After few days of installing, I can totally feel that the car is way lighter than it originally was. Slight press and can feel the acceleration is there. This is dangerous though because you will unknowingly hit 60-70 without even stepping even half of what you used to step. Money very well spent, and once my budget is back in, I think I'm likely going to come back with more stages! Thank you Nano Bros!”

“After installation of 6 stages and 1 week of run in, I just pump in 47 litre petrol with the mileage of 621 km for my CX5 2.0. For a car with 1600 kgs weight can achieved 13.2 km/L (7.5 L/100 km) was fabulous compare to my past 6 month drives with 47 litre petrol with the mileage of 520 km. This is only the mileage improved but not yet mentioned about the power sluggish improve. With this minor calculation, ROI would be around 8 months but it’s come with 7 years warranty. Never try and you will never know and feel. I have tried and feel it with satisfied result.”

“The price you pay for, not only improve performance and much better fuel consumption but lots of knowledge and superb advice from a car enthusiastic that money can’t buy. BE THERE OR BE SQUARE! JUST SIMPLY HIGHLY RECOMMENDED!!!”

“Friendly bros and quick installation. No regrets, after installation of stage 4. Can feel the faster throttle response and smoother acceleration. Enjoying my ride every day now. Thank u, Lionel and Leonard!”

“Thank you to the two bros from Gewinnen who gave me a detailed explanation on how the product works. They went an extra mile to give me valuable suggestions on how I can improve my car performance without compromising the fuel economy. Personally, I am more of a performance guy and their suggestions led me take the car to the next level. I would highly recommend them for anyone that is looking for performance and fuel economy. It's very rare to see these both going hand in hand.”

“Honestly, I was relatively skeptical of the product at first, but in view of the countless numbers of positive reviews Gewinnen had on their FB page, I decided to take a leap of faith and give the 4 Stage installation a shot and I have to say that this is the best decision I have ever made. All I can say is that this modification brought out the hidden potential of my car. The throttle now feels a lot lighter and more responsive. The engine is also now a whole lot quieter. Basically, the driving experience has improved and I have to say that I enjoy driving my car even more now.”

“A last minute arrangement with Lionel and he was kind enough to accommodate. driving a 16 years old Lexus GS300 and although a smooth and decent ride, just felt that it was lacking in the throttle response...went ahead with Stage 4 and immediately after the works, a stark difference in the pickup...no longer sluggish... the overall process was quick and had an enjoyable conversation with both brothers who were a joy and straightforward...Will be taking their advice on some minor servicing to be done will be updating them on the FC in due time...”

“Lionel and Leonard are legit in their product. Install stage 5 and felt immediate response on acceleration. I had half tank on last Sunday when install the product and can last me till today Fri before the top up. Despite the performance i am impressed on the fuel consumption which certainly improve albeit having 2500cc. Worth the $$$, thank you so much to both brothers❤️”

“Saw a lot of positive review on nano ionizer and decided to give it a try. At first I kept thinking that it’s a 50-50 chance of getting a better fc.i decided to give it a try and to my surprise,my fc was so good that I didn’t expect that I’m able to reach those numbers.the guy know his product very well and very knowledgeable.its very addictive as I always wanting to up stage more and more stages 🤣 definitely recommend 💯”

“Saw this ad kept appearing on facebook and decided to give it a try. Did not regret trying as they are friendly and helped me to improve my car’s performance and fuel efficiency and now my car does not feel sluggish in terms of acceleration and also rides has been smoother as well. Highly recommended. I myself even considering going back to them for stage 5.”

“Let me share with you I’m the guy who is very skeptical about this kind of products as I have tried something similar before and it does not work at all. But after seeing so many good reviews, I decided to give it a shot as I felt that my ride does not perform to what it supposed to. *Noted: my car is stock. So I met up with the 2 gentlemen with an open and positive mind. They began to share with me some of the car knowledge, explai… See more”

“I was contemplating about the product until i went over to give it a try. Kid you not, the car turns out like a monster ! Smooth and powerful, i recommend to all drivers to meet our friends here to give it a try ! 😄”

“Seen alot of positive reviews and has been itching to try. In the end decided to go for stage 4. Both Brothers were extremely friendly and ready to share their knowledge. Quick work was done for my car and i can feel the difference the moment i put my foot on the pedal. As im a little sensitive to my drive and pedal response. It was all worth it although during the process i was a beginning to doubt my choice to do it. 🤣 But the moment it was done, and i put my foot to the pedal. i know it was all worth it. FC wise, i believe its slowly adapting? As i can slowly feel my FC getting better. Definitely recommended for car lovers and drivers who wants the best for their car. ⭐⭐⭐⭐⭐”

“Combo Stage 1 to 4: Accelerator-to-Car Pickup improvement (eventhough some engine parts wear-and-tear, eg. Rocker Cover Gasket leakage, Valve Seat Seals in wear-and-tear, oily basic spark plugs; which contributed to engine cold start and in long term rough engine idling below 1,000 rpm). 5th Stage upgrade - Engaged their service again: Sent to authorize car workshop for necessary car parts change with back to its default condition. Brief engine crank as compared before and experienced great fuel efficiency (reset my average fuel consumption per 100km results minimum 18km/l to 20km/l for my SX4 2008).”

“Had a fun and enriching session with Lionel and Leonard. During our discussion, can really feel their passion towards cars. As for the product, I went for stage 4 and it really works. Throttle became more sensitive and FC saving from 9km/l to 18km/l (wtf, I know). For those that are still hesitant, just go and try. Won't regret! Good job guys!!”

“Very skeptical about how the product is, no modification needed to be done and can still save petrol. Tried it out first with the power supply cable installation only 2007 wish able to save from 11.0km/l to 12.4km/l is not much cause i only install one stage but im able to see the guaranteed 5-10% of fuel saving half tank 521.1km no joke. In terms of power, my acceleration have never been smoother, my rev is lower when cruising. Definitely will recommend to my friends.”

“Saw their ad on FB to improve performance and fuel consumption, so i thought why not? Since i planned to use my car for grab, every bit of improvement in fuel consumption matters. However, since this was my first car, i barely knew much about what's normal and what's not. Only when i brought my car to them we realised that my fuel consumption was terrible. It was at 6.3km/L. They laughed when i told them i think it's not bad and followed up with proof of people of the same car (brand and model and of the same year) who actually thought 9.5km/L was bad. That meant mine was way worse! So i requested for the full 5+ stages of the Gewinnen Ionisation. Afterwards they educated me alot on other ways to improve my fuel consumption and what i can do to best take care of my COE car so that it can last the remaining years. Installation of their product was 19 Feb 2023. Now 7 Apr 2023, my fuel consumption is at 9.0km/L! Still bad, compared to the norm...but i am definitely happy and satisfied! That is an increase of 2.7km/L. With a full tank of 60L meant i get to drive an additional of about 160km! I am just really happy, hence this review. If you are reading this, go and try their product, cause all other reviews say the same thing, that it works! Thanks again guys! For the installation of your product and for the free education hahaha! Still waiting for your stickers/decal 🙂”

“These guys really need to be known to all drivers who wish to improve their vehicle performance.. I am so so happy that I went to them toboost my car performance.. My estima have so much more power after the installation.. The pick up and acceleration is so much faster and smoother.. I even need to mention that I cant feel the vibration or sound of engine when im on idle or driving.. I am so impress and what they help with my car.. fuel coonsumption is also much more saving. Guys Dont hesitate anymore . These guys are so so so much recommended.. My honest opinion.. No bluff one.. dun tink twice.. Just goooo... I cant say how much I want to recommend u all but really it is WORTH IT.. I am so much happy with my car performance now. So much more happy I went to them..”

“Highly recommended after installing stage 1+2+3+4. Can straight feel the car is different and no need to accelerate more. The car feels more lighter & torquey. Driving up slope is better. Thanks bros.. 👍”

“Initially did not know much about such technology as not many such services in Singapore. Decided to give this a try, and there was definitely a significant improvement in my acceleration. Previously there was a lag and hesitation, but after this, my acceleration was instantaneous much smoother. Recommend to try at least once to feel the transition. 👍”

“Of course i will give an honest review... So just now after i tried.. acceleration is better... Smoother than i thought it will be.. Power on acceleration is subtle... But can feel the difference.. I understand my car not build for acceleration due to weight and size.. But.. let's skip to the good part.. The mid range and top end is superb!! .. Superfly!... Its banging..! And no more jerky feeling during gear changing at 5000+rpm... Really² much smoother now but with additional power... I was at gear 5 driving at 110km/hr on ECO mode .. hahah thats super super good.. really good... I have not changed my spark plugs yet.. but once i did change i update u again... For the FC i will take note and update u in a week time... Overall i am satisfied and astounding .. really works for my B class...👍🏽👍🏽👍🏽👍🏽👍🏽 good job bros! Thank u for the good service i had.. ⭐⭐⭐⭐⭐”

“Did the stage 1 to 4 and to my surprise, the drive is so smooth that caught me by surprise. Reasonable price and no modification. Highly recommend.”

“Both Lionel and his brother were really forthcoming with information and explanations on their product. It was an absolute joy to deal with them and chat about car mods and dogs. Thank you both for boosting my car. It flies better and more efficient now. 😂 I must be careful of hidden TPs and speed traps now.”

“I've been following this page since their early days but was hesitant to engage them as I was selling the previous car. Finally installed all 4 stages and the two brothers went out of their way to provide additional assistance and information for my car. Initial changes noticed after the installation is the throttle is lighter and the FC kept getting better even in full 100% city drive. So far till date I have achieve an increase in 1.5km/L from the meter readings and actual manual calculation of fuel consumption. The installation is still in the early stages but the immediate improvements is noticeable so far and the process took less than an hour. Lionel and Leonard are super helpful and are well versed with their product and other car related matters. We spent a considerable amount of time discussing parts upgrade, driving dynamics and etc. Thank you Lionel and Leonard, would have engaged you guys earlier if I was not selling the old car.”

“Very Surprise with the end result. instant feel can get the difference. caution to those whom wanna install. "Speeding is an offence"”

“Installed 1-4 stages on my VW CC 2.0 and immediately feel the difference. Car is more responsive and hardly any feel of turbo lag. Able to deliver so much power at lower rpm, that I need to adjust lighter taps on the accelerator to control speed. Fuel consumption drastically improved - on same route before installation 15L/100km, after installation around 10L/100km. Very highly recommended and also the bosses very knowledgeable and friendly, can definitely take their advice for your car.”

“highly recommended did stage 1 to 4 the power can feel the difference and the acceleration and gear change smooth 👍👍”

“highly recommended after trying out the product acceleration and response feel alot smoother and light fuel consumption also improved thanks the 2 bro for this product 👍”

“I driving a Subaru Impreza hutchback just after install stage 1 + 2 and drive from toa payoh drive back to bukit batok the distance was so shot but can already feel the car is different and I no need to accelerate more although I had throttle control..my car feels more lighter and drive up to the MSCP is better.. I will come back for stage 3 n 4. Thanks bros.”

“Im driving a VW Touran 2011 car. I must say the two brothers are very genuine and honest in their installation. Personally test drive my car to ‘feel’ the before and after. Did stage 1+2. Steering wheel was more lighter (surprisingly), up gear and down gear more smooth in the sense car was less jerky, gear change and speed picked up with lower rpm. Will be coming back for 3+4 to see more result after fixing the car health issue first 😅”

“A pair of very knowledgeable brothers that freely dispenses valuable information about your car and how to improve its condition. They are also willing to answer questions and share contacts after the service is completed. Thank you so much, enjoying the speedier drive now.”

“Did stage 4 at one go after recommendation by my friend and also reading up the reviews on their page. Am driving a 2013 MB C180 CGI with a stage 1 ECU tune and the car just feels so alive now after the nano ionisation. These are the following benefits I have experienced : 1. Smoother acceleration and pick up. 2. Greatly improved FC. Used to be able to do 150km - 180km per 1/4 tank but am doing 200km per 1/4 tank now. Based on my fuel tank capacity of 60L , that's 13km/L. Initially it may seem that the benefits are not obvious but it takes some time to stabilise as the ECU takes some time to re learn and adapt. Give it about 1 to 4 weeks depending on the health of your car. Lionel and Leonard are both extremely easy going and friendly and give post sales advise sincerely and you can feel that they only want the best for your ride. It may seem too good to be true that some stickers can improve performance that much but you have to try it to believe. I wouldn't call it magic koyok but its more like a breakthrough technology that would benefit your car and is a great complement to any tuning. I have recommended this to many fellow drivers and would definitely do stage 5 if it's available! Update : 19 Jul 2022. 230km achieved on 1/4 tank ( 13% improvement compared to previous best mileage achieved on 08 Apr 2022 ) Product still doing its magic ! absolutely awesome. 💯 Changes : 1. Added S*P Complete Fuel System Cleaner to S*C 95 after experiencing some loss of power and acceleration.( Did help with restoration but FC didn't change.) 2. Switched to C****X 95 from the usual S*C 95 as advised by Lionel before and that's when I got the current mileage. Conclusion : These 2 bros really know their stuff and their advise is spot on. Try it to believe. See less”

“They are too good to describe. They know their product well. And they also go extra mile to guide me thru the process and recommend thing that will improve my car performance. Awesome Jobs guys👍🏻👍🏻👍🏻 I’m so satisfy with my car now and it’s become like a wild horse running on the road 🐎🐎”

“The product looks simple but it works like magic, improve my horsepower and torque. And best of all fuel saving. Very good products.”

“At first when they explained, I was unsure of these 'camoflage koyoks'. How can these help to improve my car performance? But decided to give it a try on all the 4-steps when I saw the sincerity in them. They even help me with my car and pin-point the problems that I should take car of and we talked like we known each others for years while doing my car🤣. And true enough my car now sliced the road like cake hahha. Smooth ,pick up,gear change are all improved. Thumbs up to both brothers. Highly recommended!!!! Give it a try and u will know what i mean😊”

“Wonderful job done by the 2 brothers. Rlly felt improvement right after product is installed. Gave lots of advice on how to max the potential of the engine. Very highly recommended!”

“Overall I’m really satisfied with their product! After doing all the stages from 1 to 4, I can notice my car is more responsive and lighter. For FC wise definitely a lot better than before. Now I’m driving my car without Eco mode and the FC is better than with Eco mode on previously before I did all the stages. And the 2 brothers are very knowledgeable and professional with their products! Can recommend to others with a peace of mind 👍🏻”

“Both Lionel and Leonard are friendly and very knowledgeable. Just did all 4 stages yesterday. Car is more responsive. Strongly recommended their services.”

“First of all, I don’t usually write a review, but I am keen to write for this “koyok” thingy. I was looking for further engine responsivenss as my car is a non turbo engine and wanted to increase driving experience for fun. To add some histories, my car has upgraded to air speed (closed box) with shorter air intake and installed with XLR racechit. As a results, the car is far responsive as compared to stock. I happened to saw this advertisement about Nano Ionisation in FB and I was just like many others with or without technical knowledge, how some nano tapes can help to improve engine responsiveness and results in fuel saving? It makes no sense right? I laughed loud to be honest, but after reading many reviews, it seems proven. My curiosity booked the next day appointment with full stages (4 stages in a go), I must be crazy for all 4 stages in a go right? but I just wanted to try the max effects since I am spending money already. On the installation day, met Lionel and other gentlemen, they are nice and experience in car performance upgrades. When I saw the tapes, I wanted to laugh again, but I controlled as they look very professional and show 100% confident on their product. To be honest, it is just to paste a few tapes here and there, I can feel how people look at it with strong skeptical. I really didn’t believe it, but I hope it works. After installation, start the car and go for a short sprint within the car park (short distance lah), feel some improvement in engine response, but I tell myself it is just my mindset as I spent money and my mind may leaning to yes, yes, yes very power now…, u know what I mean… But I can’t say no either as I don’t race in a multi story carpark and can’t tell right?😀 so I say goodbye and left for more testing. I know my car well, I know my car’s response in certain speed, gear change and acceleration. Tested for 1 night and 1 day with my regular driving habits and routes, guess what? It actually improved in engine responsiveness and the gear change is faster. Fuel saving will be measured after 1 or 2 tanks, but so far on my regular route to work, I got 15.6km/l as compared to 15.1km/l as before. It really works like magic and I enjoyed very much. This review is purely for my experience sharing, believe it or not, go try and find out yourself. Thanks for reading this lengthy review.”

“The Nano Brothers are AWESOME ! Did up my Stage 4 today and I have to say not only were they professional and efficient thru out the whole process . The advise they gave me about my car was GOLDEN ! I learnt so much from them in that 30 mins . My car now starts up faster and it is so much smoother . Had such a great time and I would definitely recommend this to anyone . Nano bros 4 LIFE ! 🌟🌟🌟🌟🌟”

“Amazing product! I am driving Opel Mokka and my throttle response became more sensitive and my car became smoother & quieter after installation. Fuel savings increased from 18.18km/litre to 20.83km/litre. So I’m finally back on this update again. Stage 4 is really working well Even though I’m on 19” wheels So here what happened . I was having some issues with “ high “ idle rpm Then installed raizin voltage stabiliser. After that awesome wiring work by workshop mech I went to look for “ nano” brothers. Now moving off is very smooth. Here’s a pic of the updated fc. Proven gewinnen is good 🙂”

“Chanced upon their fb page while researching in way to improve my old car’s FC. I believe the reviews speak for itself! Lionel and his brother were not only knowledgeable , they were very engaging and provided feedback from my driving style to good advise. The installation process was smooth and quick, they requested for me to do a test run to ensure all was working well before they let me leave. The level of professionalism and dedication to their work should be testament enough. Will def be back for my new car ! Immediate results include clear throttle response and seen visible improvement on fc ! Good job guys!”

“The mod works well and there is really improvement in performance! I am equally shocked as well! Thank you so much for your kind sharing for car care and maintenance during the installation too. For fuel efficiency, from my initial calculations there are some improvements already, hope there will be more in future! 👍🏻👍🏻 am very impressed how the car react differently just by pasting those "wonderful koyok"! 😋😋”

“Wish 09 2nd Gen Today is my 4th day after installing stage 3 into my car....I know its gonna be a difference but its a matter of time and i dont expect it to be early. On the day itself i can feel slight improvements after installing. The car was with better response during overtaking and taking off but i did not focus much on fuel consumption. 2nd day i only drive for 45km only 2hrs Travelling time..... 3rd day driving for 109km only for 4.5hrs and observed that my car response improves and give me as I demand and also notice that my fuel tank gauge at 3/4 for 316km covered. Normally at this fuel level it can only cover 200km-230km......seeing is believing......I am going to use up my fuel till the fuel reserved lights up and will clock the mileage again .....No regrets Installing.....will meet 2 bros who is good, friendly and knowledgeable .....”

“A bit sceptical about this product. After reading all the positive reviews, decided to try it out. Went straight for full stage 3 installation. Two bros were absolutely friendly and confident about their product. Willing to share a lot invaluable experiences too. Was asked to try the ride after installation. Immediately could feel the car was lighter and more eager to rev. After a few days of driving, I could confirm that the tapes really work! Acceleration is better and the engine is able to rev more freely. Gear change also smoother, making my ride more joyful and confident, especially overtaking at low speed as my ride is heavy. I can say these magical tapes are really best bang for buck! Not forgetting it is one of the safest mod in the market. Highly recommended to those who want to improve their car's responses. Still monitoring the fuel consumption but I am satisfied with the product!”

“just done it really good n value money,no worries u pay first later all u take back,why?I tell you all now before do this nano my old altis full tank 50 run less than 500km,done this nano now second full tank run close to 600km really value for money.”

“To be honest, I was a little skeptical at first about the fuel saving and power increase. However after looking through the review I gave it a try for Stage 1+2+3. Both the brothers were friendly and very confident in their product. After the fix they ask me to go for a test drive. Immediately I felt the difference, at first I thought my mind was playing tricks on me. After awhile I can feel the paddle is lighter and I don’t need to paddle as hard like how I use too. I was finding ways to save fuel and this is definitely the solution to it! From my first full load of fuel I am able to see improvement! Look at the attached pictures 😉 Great work guys!”

“My Attrage is usually quite slow in moving off. I was sceptical about this product. After installating stage 1 and had covered about 15km so far, I can say that the throttle response has improved especially when moving off from stationary. The car felt alive, like having a shot of espresso coffee when you wake up. I will have to monitor on the fc in the next couple of weeks. Overall experience was good, bros were friendly too. For those who seek improvement in performance of their car can try it out, worth it.☺️”

“Had a minor scare when FC went up after installation. but the owners assured me and eventually the FC got better. 50km more for 95 octane fuel (550km to 600km mileage for 3/4 tank) and 80km more for X-Power (600km to 680km mileage for 3/4 tank). Overall, worth it! Not forgetting to mention that they referred me to their mechanic for car maintenance when my workshop messed up and also gave me some tips for car performance matters. Going beyond what is required. 👍 Edit: Clarified on some query and updated the review.”

“I am driving a insignia , recently found this two Brother on Facebook about fuel saving tape and it give me the interest to try it out , at start I tend not to belive Cus is just a few tape sticking on part of the car engine , but after sticking it , and driving it for few days my fuel consumption from 9.8l per 100km Drop to 6.9 per 100km which drastically give me a very good fc after that , and I am surprise to it, so for this tape service I would highly reccomand”

“I am driving an Opel Astra K 1.4T . After applying the tapes, my throttle became more responsive than before. The turbo lag has been reduced as well. Fuel consumption has dropped from 8.5L/100km to 7.5L/100KM Amazing product to help with Fuel consumption and throttle responsiveness.”

“I'm driving a Lexus RX270. 4 cylinders capacity on a large SUV body. Pick up power is normal compromised, especially during overtaking or approaching up slope. Now can feel the diff after installation 2 days ago. The power is there. Engine smoother and quieter. Now monitoring the fuel saving. Worth the investment. Cool!”

“First Honda FC 1.5T to install the tape all stage 3 done. I shall not talk about the comfort of the drive as each to its own. Numbers dun lie on my lufi meter, my air intake increase and stock car's turbo can easily reach 0.4-0.5 boost in a heartbeat ... before that it was quite a struggle. Fuel consumption went down on my drive home will monitor more. Honda Civic fc owners should give it a shot.”

“Just installed on my QashQai 2018. Went full all 3 stages. immediately felt the car, previously rather sluggish bcos 1.2 Turbo, giving way better pickup and responses, even in reverse gear. now i have better confidence to come out from junctions, overtaking etc. FC wise cannot tell yet, but will continue to monitor. Thanks bro for this magical Ko-yoke hahaha... hard to believe they WORK! one word...AWESOME!”

“Done up 3 stages at a go on my Suzuki swift. Could tell the difference, i must say the engine has became more smooth, responsive and silent. Both brothers are very friendly and knowledgeable about their product. Understand that majority of the people might think it might be a hoax but i will attest to it, you will have to see to believe it! Light pedal and you will know difference from before and after. Will continue to monitor the FC since done fresh from the oven”

“Was quite skeptical about this product, but nevertheless decide to give it a try. The results are worth the try. Car is more responsive with increased power, driving becomes smoother with lesser noise. Still testing fuel consumption. Hopefully to see an increase of mileage. The brothers are generous to share every knowledge about cars, even after sales. A good advisor to consult if you wish to mod your car Keep up the good work guys!”

“Did all 3 stages for my mini. Car engine become more smooth , responsive & quiet. Both brothers are very knowledgeable and helpful. Learned a lot from the both of them. Those magical tapes I wish I can tape my whole car. Thank u Guys. Way to go! Will lookout for my fuel consumption though. As I just tape a couple days. Thank you brothers once again!”

“I would really recommend them to you as they are very honest people doing the business.. My toyota sienta was consuming alot of fuel about 13.5km/l despite doing the routine maintenance.. After doing stage 6, immediately, my car was feeling more responsive and light, so i was expecting a save on the fuel consumption. However, up to 6th tank, i noticed there was no changes in fuel consumption, despite on the huge difference in power delivery. I pm them, and they requested me to do a catalytic converter clean for my car, in which i did. Just after only 1 trip, the car was consuming at only 18.6km/l !! ..very huge difference! It was very smoooth like butter! I will definitely come back for more! Now.. driving is soo fun and really enjoyable !! thank you!!”

“Hey bro, a quick one-month update. The car continues to deliver a very pleasant and enjoyable driving experience. Gear changes remain smooth, idling vibrations are minimal, and the overall drive feels solid and reliable, which definitely inspires greater confidence behind the wheel. Power delivery is also well-judged, coming in smoothly and effortlessly when overtaking is needed. The biggest surprise, is the fuel efficiency — 7.4L/100km (13.1km/L). I genuinely never expected this from a 1.6-tonne executive sedan with a turbocharged petrol engine (non-hybrid). Previously, I was averaging around 13.1L/100km. Thank you, Gewinnen.”

“How is it that my average fuel consumption (Toyota Noah 1.8 R90 Hybrid) as shown on my odometer after installing Gewinnen products dropped from 18.7km/l to 18.1km/l but I am getting more mileage per full tank jumping from 850km to 950km and more? This looks contradictory at first, but it actually makes sense once you understand how the car calculates fuel consumption versus how real-world range works. Short Answer By ChatGPT / META Your odometer’s average fuel consumption (km/l) is an estimated, behaviour-weighted number, while distance per full tank is a real, physical outcome. After installing the Gewinnen products, your engine efficiency and usable fuel delivery improved, but the dashboard calculation hasn’t fully reflected that yet and in some cases, it never perfectly will. ⸻ So why the numbers don’t line up 1. The trip computer is an estimate, not a fuel meter Your car does not measure fuel burned directly. It estimates consumption using: • Injector pulse width • Engine load • Throttle input • Short-term driving patterns After installing Gewinnen parts (better airflow, smoother combustion, reduced drag), those assumptions can become slightly off. So: • The displayed km/l drops • But actual fuel usage improves This is very common after intake, exhaust, or friction-reducing upgrades. So Gewinnen product works. ⸻ 2. Driving behaviour changed without you realising With better response and torque: • You accelerate more smoothly • Less throttle is needed to maintain speed • Gear changes happen earlier • Engine spends more time in efficient RPM ranges But the trip computer may still “penalise” brief accelerations even though they burn less total fuel. Result: • Lower average km/l shown • Higher total distance travelled ⸻ 3. Average km/l is time-weighted, not distance-weighted If your recent driving includes: • More short trips • Cold starts • Traffic crawling The km/l average drops quickly. But over a full tank, your long steady cruising (where Gewinnen products shine) dominates. Tank range improves even though the displayed average worsens. ⸻ 4. You’re extracting more usable fuel from the tank Two subtle effects often happen: • More complete combustion • Slightly leaner, cleaner burn under light load That doesn’t always show up as better km/l, but it extends usable range before the low-fuel threshold. 850 km → 950+ km is a real-world efficiency gain, not imagination. MY FINAL VERDICT IS THAT THE SILLY LOOKING STICKERS ALL OVER THE ENGINE BAY REALLY WORKS! UNBELIEVABLE! AND I DON’T GET PAID TO WRITE THIS NOR AM I RECEIVING ANY FAVOURS AFTER THIS. 🤨”

“100% recommended for anyone to feel immediate power difference! No need to doubt, take a leap of faith and book right away”

“★★★★★ Transformed My Ride & Gave Me Peace of Mind! ​I'm absolutely blown away by the results after using Gewinnen! My car had been feeling sluggish always, almost like it was struggling to keep up, and I was starting to dread my daily commute. I'd read good things about Gewinnen, so I decided to give it a try, and I am so glad I did! ​From the moment I started driving after Leonard & Lionel installed it, the difference was night and day. My car feels significantly more responsive and powerful. Acceleration is smoother, and it tackles inclines with an ease it hasn't had in ages. It's like my car has found its second wind! ​But what truly sets Gewinnen apart isn't just the immediate performance boost, it's the incredible expertise and care they showed regarding my car's overall health. Not only did they deliver on the performance promise but they also took the time to explain exactly what was contributing to my engine's condition and, more importantly, provided invaluable advice on how to improve its longevity and efficiency. They shared specific tips on what type of engine oil to use and changing spark plugs every 40k etc that I had no idea about. This proactive approach to engine care is something I truly appreciate. ​It's clear that this product isn't just about a quick fix, they genuinely care about helping you maintain your vehicle in the long run. The combination of a noticeable performance improvement and expert guidance on engine maintenance makes this product/service an absolute game-changer. ​If your car is feeling a bit tired and you want to give it a new lease on life while also getting expert advice on how to keep it running smoothly for years to come, look no further than Gewinnen. It's a 5-star experience, hands down!”

“Was skeptical when I first saw it in FB. But I decided to take the leap of faith to try and install this. Got to say this has to be the best decision ever. The Nano Bros (Lionel & Leonard) are both skillful in this area and have extensive knowledge on cars itself. They are not just skilled, they are very helpful and willing to share their knowledge with car owners who may not know outside of P,R,N,D. Haha. After few days of installing, I can totally feel that the car is way lighter than it originally was. Slight press and can feel the acceleration is there. This is dangerous though because you will unknowingly hit 60-70 without even stepping even half of what you used to step. Money very well spent, and once my budget is back in, I think I'm likely going to come back with more stages! Thank you Nano Bros!”

“After installation of 6 stages and 1 week of run in, I just pump in 47 litre petrol with the mileage of 621 km for my CX5 2.0. For a car with 1600 kgs weight can achieved 13.2 km/L (7.5 L/100 km) was fabulous compare to my past 6 month drives with 47 litre petrol with the mileage of 520 km. This is only the mileage improved but not yet mentioned about the power sluggish improve. With this minor calculation, ROI would be around 8 months but it’s come with 7 years warranty. Never try and you will never know and feel. I have tried and feel it with satisfied result.”

“The price you pay for, not only improve performance and much better fuel consumption but lots of knowledge and superb advice from a car enthusiastic that money can’t buy. BE THERE OR BE SQUARE! JUST SIMPLY HIGHLY RECOMMENDED!!!”

“Friendly bros and quick installation. No regrets, after installation of stage 4. Can feel the faster throttle response and smoother acceleration. Enjoying my ride every day now. Thank u, Lionel and Leonard!”

“Thank you to the two bros from Gewinnen who gave me a detailed explanation on how the product works. They went an extra mile to give me valuable suggestions on how I can improve my car performance without compromising the fuel economy. Personally, I am more of a performance guy and their suggestions led me take the car to the next level. I would highly recommend them for anyone that is looking for performance and fuel economy. It's very rare to see these both going hand in hand.”

“Honestly, I was relatively skeptical of the product at first, but in view of the countless numbers of positive reviews Gewinnen had on their FB page, I decided to take a leap of faith and give the 4 Stage installation a shot and I have to say that this is the best decision I have ever made. All I can say is that this modification brought out the hidden potential of my car. The throttle now feels a lot lighter and more responsive. The engine is also now a whole lot quieter. Basically, the driving experience has improved and I have to say that I enjoy driving my car even more now.”

“A last minute arrangement with Lionel and he was kind enough to accommodate. driving a 16 years old Lexus GS300 and although a smooth and decent ride, just felt that it was lacking in the throttle response...went ahead with Stage 4 and immediately after the works, a stark difference in the pickup...no longer sluggish... the overall process was quick and had an enjoyable conversation with both brothers who were a joy and straightforward...Will be taking their advice on some minor servicing to be done will be updating them on the FC in due time...”

“Lionel and Leonard are legit in their product. Install stage 5 and felt immediate response on acceleration. I had half tank on last Sunday when install the product and can last me till today Fri before the top up. Despite the performance i am impressed on the fuel consumption which certainly improve albeit having 2500cc. Worth the $$$, thank you so much to both brothers❤️”

“Saw a lot of positive review on nano ionizer and decided to give it a try. At first I kept thinking that it’s a 50-50 chance of getting a better fc.i decided to give it a try and to my surprise,my fc was so good that I didn’t expect that I’m able to reach those numbers.the guy know his product very well and very knowledgeable.its very addictive as I always wanting to up stage more and more stages 🤣 definitely recommend 💯”

“Saw this ad kept appearing on facebook and decided to give it a try. Did not regret trying as they are friendly and helped me to improve my car’s performance and fuel efficiency and now my car does not feel sluggish in terms of acceleration and also rides has been smoother as well. Highly recommended. I myself even considering going back to them for stage 5.”

“Let me share with you I’m the guy who is very skeptical about this kind of products as I have tried something similar before and it does not work at all. But after seeing so many good reviews, I decided to give it a shot as I felt that my ride does not perform to what it supposed to. *Noted: my car is stock. So I met up with the 2 gentlemen with an open and positive mind. They began to share with me some of the car knowledge, explai… See more”

“I was contemplating about the product until i went over to give it a try. Kid you not, the car turns out like a monster ! Smooth and powerful, i recommend to all drivers to meet our friends here to give it a try ! 😄”

“Seen alot of positive reviews and has been itching to try. In the end decided to go for stage 4. Both Brothers were extremely friendly and ready to share their knowledge. Quick work was done for my car and i can feel the difference the moment i put my foot on the pedal. As im a little sensitive to my drive and pedal response. It was all worth it although during the process i was a beginning to doubt my choice to do it. 🤣 But the moment it was done, and i put my foot to the pedal. i know it was all worth it. FC wise, i believe its slowly adapting? As i can slowly feel my FC getting better. Definitely recommended for car lovers and drivers who wants the best for their car. ⭐⭐⭐⭐⭐”

“Combo Stage 1 to 4: Accelerator-to-Car Pickup improvement (eventhough some engine parts wear-and-tear, eg. Rocker Cover Gasket leakage, Valve Seat Seals in wear-and-tear, oily basic spark plugs; which contributed to engine cold start and in long term rough engine idling below 1,000 rpm). 5th Stage upgrade - Engaged their service again: Sent to authorize car workshop for necessary car parts change with back to its default condition. Brief engine crank as compared before and experienced great fuel efficiency (reset my average fuel consumption per 100km results minimum 18km/l to 20km/l for my SX4 2008).”

“Had a fun and enriching session with Lionel and Leonard. During our discussion, can really feel their passion towards cars. As for the product, I went for stage 4 and it really works. Throttle became more sensitive and FC saving from 9km/l to 18km/l (wtf, I know). For those that are still hesitant, just go and try. Won't regret! Good job guys!!”

“Very skeptical about how the product is, no modification needed to be done and can still save petrol. Tried it out first with the power supply cable installation only 2007 wish able to save from 11.0km/l to 12.4km/l is not much cause i only install one stage but im able to see the guaranteed 5-10% of fuel saving half tank 521.1km no joke. In terms of power, my acceleration have never been smoother, my rev is lower when cruising. Definitely will recommend to my friends.”

“Saw their ad on FB to improve performance and fuel consumption, so i thought why not? Since i planned to use my car for grab, every bit of improvement in fuel consumption matters. However, since this was my first car, i barely knew much about what's normal and what's not. Only when i brought my car to them we realised that my fuel consumption was terrible. It was at 6.3km/L. They laughed when i told them i think it's not bad and followed up with proof of people of the same car (brand and model and of the same year) who actually thought 9.5km/L was bad. That meant mine was way worse! So i requested for the full 5+ stages of the Gewinnen Ionisation. Afterwards they educated me alot on other ways to improve my fuel consumption and what i can do to best take care of my COE car so that it can last the remaining years. Installation of their product was 19 Feb 2023. Now 7 Apr 2023, my fuel consumption is at 9.0km/L! Still bad, compared to the norm...but i am definitely happy and satisfied! That is an increase of 2.7km/L. With a full tank of 60L meant i get to drive an additional of about 160km! I am just really happy, hence this review. If you are reading this, go and try their product, cause all other reviews say the same thing, that it works! Thanks again guys! For the installation of your product and for the free education hahaha! Still waiting for your stickers/decal 🙂”

“These guys really need to be known to all drivers who wish to improve their vehicle performance.. I am so so happy that I went to them toboost my car performance.. My estima have so much more power after the installation.. The pick up and acceleration is so much faster and smoother.. I even need to mention that I cant feel the vibration or sound of engine when im on idle or driving.. I am so impress and what they help with my car.. fuel coonsumption is also much more saving. Guys Dont hesitate anymore . These guys are so so so much recommended.. My honest opinion.. No bluff one.. dun tink twice.. Just goooo... I cant say how much I want to recommend u all but really it is WORTH IT.. I am so much happy with my car performance now. So much more happy I went to them..”

“Highly recommended after installing stage 1+2+3+4. Can straight feel the car is different and no need to accelerate more. The car feels more lighter & torquey. Driving up slope is better. Thanks bros.. 👍”

“Initially did not know much about such technology as not many such services in Singapore. Decided to give this a try, and there was definitely a significant improvement in my acceleration. Previously there was a lag and hesitation, but after this, my acceleration was instantaneous much smoother. Recommend to try at least once to feel the transition. 👍”

“Of course i will give an honest review... So just now after i tried.. acceleration is better... Smoother than i thought it will be.. Power on acceleration is subtle... But can feel the difference.. I understand my car not build for acceleration due to weight and size.. But.. let's skip to the good part.. The mid range and top end is superb!! .. Superfly!... Its banging..! And no more jerky feeling during gear changing at 5000+rpm... Really² much smoother now but with additional power... I was at gear 5 driving at 110km/hr on ECO mode .. hahah thats super super good.. really good... I have not changed my spark plugs yet.. but once i did change i update u again... For the FC i will take note and update u in a week time... Overall i am satisfied and astounding .. really works for my B class...👍🏽👍🏽👍🏽👍🏽👍🏽 good job bros! Thank u for the good service i had.. ⭐⭐⭐⭐⭐”

“Did the stage 1 to 4 and to my surprise, the drive is so smooth that caught me by surprise. Reasonable price and no modification. Highly recommend.”

“Both Lionel and his brother were really forthcoming with information and explanations on their product. It was an absolute joy to deal with them and chat about car mods and dogs. Thank you both for boosting my car. It flies better and more efficient now. 😂 I must be careful of hidden TPs and speed traps now.”

“I've been following this page since their early days but was hesitant to engage them as I was selling the previous car. Finally installed all 4 stages and the two brothers went out of their way to provide additional assistance and information for my car. Initial changes noticed after the installation is the throttle is lighter and the FC kept getting better even in full 100% city drive. So far till date I have achieve an increase in 1.5km/L from the meter readings and actual manual calculation of fuel consumption. The installation is still in the early stages but the immediate improvements is noticeable so far and the process took less than an hour. Lionel and Leonard are super helpful and are well versed with their product and other car related matters. We spent a considerable amount of time discussing parts upgrade, driving dynamics and etc. Thank you Lionel and Leonard, would have engaged you guys earlier if I was not selling the old car.”

“Very Surprise with the end result. instant feel can get the difference. caution to those whom wanna install. "Speeding is an offence"”

“Installed 1-4 stages on my VW CC 2.0 and immediately feel the difference. Car is more responsive and hardly any feel of turbo lag. Able to deliver so much power at lower rpm, that I need to adjust lighter taps on the accelerator to control speed. Fuel consumption drastically improved - on same route before installation 15L/100km, after installation around 10L/100km. Very highly recommended and also the bosses very knowledgeable and friendly, can definitely take their advice for your car.”

“highly recommended did stage 1 to 4 the power can feel the difference and the acceleration and gear change smooth 👍👍”

“highly recommended after trying out the product acceleration and response feel alot smoother and light fuel consumption also improved thanks the 2 bro for this product 👍”

“I driving a Subaru Impreza hutchback just after install stage 1 + 2 and drive from toa payoh drive back to bukit batok the distance was so shot but can already feel the car is different and I no need to accelerate more although I had throttle control..my car feels more lighter and drive up to the MSCP is better.. I will come back for stage 3 n 4. Thanks bros.”

“Im driving a VW Touran 2011 car. I must say the two brothers are very genuine and honest in their installation. Personally test drive my car to ‘feel’ the before and after. Did stage 1+2. Steering wheel was more lighter (surprisingly), up gear and down gear more smooth in the sense car was less jerky, gear change and speed picked up with lower rpm. Will be coming back for 3+4 to see more result after fixing the car health issue first 😅”

“A pair of very knowledgeable brothers that freely dispenses valuable information about your car and how to improve its condition. They are also willing to answer questions and share contacts after the service is completed. Thank you so much, enjoying the speedier drive now.”

“Did stage 4 at one go after recommendation by my friend and also reading up the reviews on their page. Am driving a 2013 MB C180 CGI with a stage 1 ECU tune and the car just feels so alive now after the nano ionisation. These are the following benefits I have experienced : 1. Smoother acceleration and pick up. 2. Greatly improved FC. Used to be able to do 150km - 180km per 1/4 tank but am doing 200km per 1/4 tank now. Based on my fuel tank capacity of 60L , that's 13km/L. Initially it may seem that the benefits are not obvious but it takes some time to stabilise as the ECU takes some time to re learn and adapt. Give it about 1 to 4 weeks depending on the health of your car. Lionel and Leonard are both extremely easy going and friendly and give post sales advise sincerely and you can feel that they only want the best for your ride. It may seem too good to be true that some stickers can improve performance that much but you have to try it to believe. I wouldn't call it magic koyok but its more like a breakthrough technology that would benefit your car and is a great complement to any tuning. I have recommended this to many fellow drivers and would definitely do stage 5 if it's available! Update : 19 Jul 2022. 230km achieved on 1/4 tank ( 13% improvement compared to previous best mileage achieved on 08 Apr 2022 ) Product still doing its magic ! absolutely awesome. 💯 Changes : 1. Added S*P Complete Fuel System Cleaner to S*C 95 after experiencing some loss of power and acceleration.( Did help with restoration but FC didn't change.) 2. Switched to C****X 95 from the usual S*C 95 as advised by Lionel before and that's when I got the current mileage. Conclusion : These 2 bros really know their stuff and their advise is spot on. Try it to believe. See less”

“They are too good to describe. They know their product well. And they also go extra mile to guide me thru the process and recommend thing that will improve my car performance. Awesome Jobs guys👍🏻👍🏻👍🏻 I’m so satisfy with my car now and it’s become like a wild horse running on the road 🐎🐎”

“The product looks simple but it works like magic, improve my horsepower and torque. And best of all fuel saving. Very good products.”

“At first when they explained, I was unsure of these 'camoflage koyoks'. How can these help to improve my car performance? But decided to give it a try on all the 4-steps when I saw the sincerity in them. They even help me with my car and pin-point the problems that I should take car of and we talked like we known each others for years while doing my car🤣. And true enough my car now sliced the road like cake hahha. Smooth ,pick up,gear change are all improved. Thumbs up to both brothers. Highly recommended!!!! Give it a try and u will know what i mean😊”

“Wonderful job done by the 2 brothers. Rlly felt improvement right after product is installed. Gave lots of advice on how to max the potential of the engine. Very highly recommended!”

“Overall I’m really satisfied with their product! After doing all the stages from 1 to 4, I can notice my car is more responsive and lighter. For FC wise definitely a lot better than before. Now I’m driving my car without Eco mode and the FC is better than with Eco mode on previously before I did all the stages. And the 2 brothers are very knowledgeable and professional with their products! Can recommend to others with a peace of mind 👍🏻”

“Both Lionel and Leonard are friendly and very knowledgeable. Just did all 4 stages yesterday. Car is more responsive. Strongly recommended their services.”

“First of all, I don’t usually write a review, but I am keen to write for this “koyok” thingy. I was looking for further engine responsivenss as my car is a non turbo engine and wanted to increase driving experience for fun. To add some histories, my car has upgraded to air speed (closed box) with shorter air intake and installed with XLR racechit. As a results, the car is far responsive as compared to stock. I happened to saw this advertisement about Nano Ionisation in FB and I was just like many others with or without technical knowledge, how some nano tapes can help to improve engine responsiveness and results in fuel saving? It makes no sense right? I laughed loud to be honest, but after reading many reviews, it seems proven. My curiosity booked the next day appointment with full stages (4 stages in a go), I must be crazy for all 4 stages in a go right? but I just wanted to try the max effects since I am spending money already. On the installation day, met Lionel and other gentlemen, they are nice and experience in car performance upgrades. When I saw the tapes, I wanted to laugh again, but I controlled as they look very professional and show 100% confident on their product. To be honest, it is just to paste a few tapes here and there, I can feel how people look at it with strong skeptical. I really didn’t believe it, but I hope it works. After installation, start the car and go for a short sprint within the car park (short distance lah), feel some improvement in engine response, but I tell myself it is just my mindset as I spent money and my mind may leaning to yes, yes, yes very power now…, u know what I mean… But I can’t say no either as I don’t race in a multi story carpark and can’t tell right?😀 so I say goodbye and left for more testing. I know my car well, I know my car’s response in certain speed, gear change and acceleration. Tested for 1 night and 1 day with my regular driving habits and routes, guess what? It actually improved in engine responsiveness and the gear change is faster. Fuel saving will be measured after 1 or 2 tanks, but so far on my regular route to work, I got 15.6km/l as compared to 15.1km/l as before. It really works like magic and I enjoyed very much. This review is purely for my experience sharing, believe it or not, go try and find out yourself. Thanks for reading this lengthy review.”

“The Nano Brothers are AWESOME ! Did up my Stage 4 today and I have to say not only were they professional and efficient thru out the whole process . The advise they gave me about my car was GOLDEN ! I learnt so much from them in that 30 mins . My car now starts up faster and it is so much smoother . Had such a great time and I would definitely recommend this to anyone . Nano bros 4 LIFE ! 🌟🌟🌟🌟🌟”

“Amazing product! I am driving Opel Mokka and my throttle response became more sensitive and my car became smoother & quieter after installation. Fuel savings increased from 18.18km/litre to 20.83km/litre. So I’m finally back on this update again. Stage 4 is really working well Even though I’m on 19” wheels So here what happened . I was having some issues with “ high “ idle rpm Then installed raizin voltage stabiliser. After that awesome wiring work by workshop mech I went to look for “ nano” brothers. Now moving off is very smooth. Here’s a pic of the updated fc. Proven gewinnen is good 🙂”

“Chanced upon their fb page while researching in way to improve my old car’s FC. I believe the reviews speak for itself! Lionel and his brother were not only knowledgeable , they were very engaging and provided feedback from my driving style to good advise. The installation process was smooth and quick, they requested for me to do a test run to ensure all was working well before they let me leave. The level of professionalism and dedication to their work should be testament enough. Will def be back for my new car ! Immediate results include clear throttle response and seen visible improvement on fc ! Good job guys!”

“The mod works well and there is really improvement in performance! I am equally shocked as well! Thank you so much for your kind sharing for car care and maintenance during the installation too. For fuel efficiency, from my initial calculations there are some improvements already, hope there will be more in future! 👍🏻👍🏻 am very impressed how the car react differently just by pasting those "wonderful koyok"! 😋😋”

“Wish 09 2nd Gen Today is my 4th day after installing stage 3 into my car....I know its gonna be a difference but its a matter of time and i dont expect it to be early. On the day itself i can feel slight improvements after installing. The car was with better response during overtaking and taking off but i did not focus much on fuel consumption. 2nd day i only drive for 45km only 2hrs Travelling time..... 3rd day driving for 109km only for 4.5hrs and observed that my car response improves and give me as I demand and also notice that my fuel tank gauge at 3/4 for 316km covered. Normally at this fuel level it can only cover 200km-230km......seeing is believing......I am going to use up my fuel till the fuel reserved lights up and will clock the mileage again .....No regrets Installing.....will meet 2 bros who is good, friendly and knowledgeable .....”

“A bit sceptical about this product. After reading all the positive reviews, decided to try it out. Went straight for full stage 3 installation. Two bros were absolutely friendly and confident about their product. Willing to share a lot invaluable experiences too. Was asked to try the ride after installation. Immediately could feel the car was lighter and more eager to rev. After a few days of driving, I could confirm that the tapes really work! Acceleration is better and the engine is able to rev more freely. Gear change also smoother, making my ride more joyful and confident, especially overtaking at low speed as my ride is heavy. I can say these magical tapes are really best bang for buck! Not forgetting it is one of the safest mod in the market. Highly recommended to those who want to improve their car's responses. Still monitoring the fuel consumption but I am satisfied with the product!”

“just done it really good n value money,no worries u pay first later all u take back,why?I tell you all now before do this nano my old altis full tank 50 run less than 500km,done this nano now second full tank run close to 600km really value for money.”

“To be honest, I was a little skeptical at first about the fuel saving and power increase. However after looking through the review I gave it a try for Stage 1+2+3. Both the brothers were friendly and very confident in their product. After the fix they ask me to go for a test drive. Immediately I felt the difference, at first I thought my mind was playing tricks on me. After awhile I can feel the paddle is lighter and I don’t need to paddle as hard like how I use too. I was finding ways to save fuel and this is definitely the solution to it! From my first full load of fuel I am able to see improvement! Look at the attached pictures 😉 Great work guys!”

“My Attrage is usually quite slow in moving off. I was sceptical about this product. After installating stage 1 and had covered about 15km so far, I can say that the throttle response has improved especially when moving off from stationary. The car felt alive, like having a shot of espresso coffee when you wake up. I will have to monitor on the fc in the next couple of weeks. Overall experience was good, bros were friendly too. For those who seek improvement in performance of their car can try it out, worth it.☺️”

“Had a minor scare when FC went up after installation. but the owners assured me and eventually the FC got better. 50km more for 95 octane fuel (550km to 600km mileage for 3/4 tank) and 80km more for X-Power (600km to 680km mileage for 3/4 tank). Overall, worth it! Not forgetting to mention that they referred me to their mechanic for car maintenance when my workshop messed up and also gave me some tips for car performance matters. Going beyond what is required. 👍 Edit: Clarified on some query and updated the review.”

“I am driving a insignia , recently found this two Brother on Facebook about fuel saving tape and it give me the interest to try it out , at start I tend not to belive Cus is just a few tape sticking on part of the car engine , but after sticking it , and driving it for few days my fuel consumption from 9.8l per 100km Drop to 6.9 per 100km which drastically give me a very good fc after that , and I am surprise to it, so for this tape service I would highly reccomand”

“I am driving an Opel Astra K 1.4T . After applying the tapes, my throttle became more responsive than before. The turbo lag has been reduced as well. Fuel consumption has dropped from 8.5L/100km to 7.5L/100KM Amazing product to help with Fuel consumption and throttle responsiveness.”

“I'm driving a Lexus RX270. 4 cylinders capacity on a large SUV body. Pick up power is normal compromised, especially during overtaking or approaching up slope. Now can feel the diff after installation 2 days ago. The power is there. Engine smoother and quieter. Now monitoring the fuel saving. Worth the investment. Cool!”

“First Honda FC 1.5T to install the tape all stage 3 done. I shall not talk about the comfort of the drive as each to its own. Numbers dun lie on my lufi meter, my air intake increase and stock car's turbo can easily reach 0.4-0.5 boost in a heartbeat ... before that it was quite a struggle. Fuel consumption went down on my drive home will monitor more. Honda Civic fc owners should give it a shot.”

“Just installed on my QashQai 2018. Went full all 3 stages. immediately felt the car, previously rather sluggish bcos 1.2 Turbo, giving way better pickup and responses, even in reverse gear. now i have better confidence to come out from junctions, overtaking etc. FC wise cannot tell yet, but will continue to monitor. Thanks bro for this magical Ko-yoke hahaha... hard to believe they WORK! one word...AWESOME!”

“Done up 3 stages at a go on my Suzuki swift. Could tell the difference, i must say the engine has became more smooth, responsive and silent. Both brothers are very friendly and knowledgeable about their product. Understand that majority of the people might think it might be a hoax but i will attest to it, you will have to see to believe it! Light pedal and you will know difference from before and after. Will continue to monitor the FC since done fresh from the oven”

“Was quite skeptical about this product, but nevertheless decide to give it a try. The results are worth the try. Car is more responsive with increased power, driving becomes smoother with lesser noise. Still testing fuel consumption. Hopefully to see an increase of mileage. The brothers are generous to share every knowledge about cars, even after sales. A good advisor to consult if you wish to mod your car Keep up the good work guys!”

“Did all 3 stages for my mini. Car engine become more smooth , responsive & quiet. Both brothers are very knowledgeable and helpful. Learned a lot from the both of them. Those magical tapes I wish I can tape my whole car. Thank u Guys. Way to go! Will lookout for my fuel consumption though. As I just tape a couple days. Thank you brothers once again!”

“I would really recommend them to you as they are very honest people doing the business.. My toyota sienta was consuming alot of fuel about 13.5km/l despite doing the routine maintenance.. After doing stage 6, immediately, my car was feeling more responsive and light, so i was expecting a save on the fuel consumption. However, up to 6th tank, i noticed there was no changes in fuel consumption, despite on the huge difference in power delivery. I pm them, and they requested me to do a catalytic converter clean for my car, in which i did. Just after only 1 trip, the car was consuming at only 18.6km/l !! ..very huge difference! It was very smoooth like butter! I will definitely come back for more! Now.. driving is soo fun and really enjoyable !! thank you!!”

“Hey bro, a quick one-month update. The car continues to deliver a very pleasant and enjoyable driving experience. Gear changes remain smooth, idling vibrations are minimal, and the overall drive feels solid and reliable, which definitely inspires greater confidence behind the wheel. Power delivery is also well-judged, coming in smoothly and effortlessly when overtaking is needed. The biggest surprise, is the fuel efficiency — 7.4L/100km (13.1km/L). I genuinely never expected this from a 1.6-tonne executive sedan with a turbocharged petrol engine (non-hybrid). Previously, I was averaging around 13.1L/100km. Thank you, Gewinnen.”

“How is it that my average fuel consumption (Toyota Noah 1.8 R90 Hybrid) as shown on my odometer after installing Gewinnen products dropped from 18.7km/l to 18.1km/l but I am getting more mileage per full tank jumping from 850km to 950km and more? This looks contradictory at first, but it actually makes sense once you understand how the car calculates fuel consumption versus how real-world range works. Short Answer By ChatGPT / META Your odometer’s average fuel consumption (km/l) is an estimated, behaviour-weighted number, while distance per full tank is a real, physical outcome. After installing the Gewinnen products, your engine efficiency and usable fuel delivery improved, but the dashboard calculation hasn’t fully reflected that yet and in some cases, it never perfectly will. ⸻ So why the numbers don’t line up 1. The trip computer is an estimate, not a fuel meter Your car does not measure fuel burned directly. It estimates consumption using: • Injector pulse width • Engine load • Throttle input • Short-term driving patterns After installing Gewinnen parts (better airflow, smoother combustion, reduced drag), those assumptions can become slightly off. So: • The displayed km/l drops • But actual fuel usage improves This is very common after intake, exhaust, or friction-reducing upgrades. So Gewinnen product works. ⸻ 2. Driving behaviour changed without you realising With better response and torque: • You accelerate more smoothly • Less throttle is needed to maintain speed • Gear changes happen earlier • Engine spends more time in efficient RPM ranges But the trip computer may still “penalise” brief accelerations even though they burn less total fuel. Result: • Lower average km/l shown • Higher total distance travelled ⸻ 3. Average km/l is time-weighted, not distance-weighted If your recent driving includes: • More short trips • Cold starts • Traffic crawling The km/l average drops quickly. But over a full tank, your long steady cruising (where Gewinnen products shine) dominates. Tank range improves even though the displayed average worsens. ⸻ 4. You’re extracting more usable fuel from the tank Two subtle effects often happen: • More complete combustion • Slightly leaner, cleaner burn under light load That doesn’t always show up as better km/l, but it extends usable range before the low-fuel threshold. 850 km → 950+ km is a real-world efficiency gain, not imagination. MY FINAL VERDICT IS THAT THE SILLY LOOKING STICKERS ALL OVER THE ENGINE BAY REALLY WORKS! UNBELIEVABLE! AND I DON’T GET PAID TO WRITE THIS NOR AM I RECEIVING ANY FAVOURS AFTER THIS. 🤨”

“100% recommended for anyone to feel immediate power difference! No need to doubt, take a leap of faith and book right away”

“★★★★★ Transformed My Ride & Gave Me Peace of Mind! ​I'm absolutely blown away by the results after using Gewinnen! My car had been feeling sluggish always, almost like it was struggling to keep up, and I was starting to dread my daily commute. I'd read good things about Gewinnen, so I decided to give it a try, and I am so glad I did! ​From the moment I started driving after Leonard & Lionel installed it, the difference was night and day. My car feels significantly more responsive and powerful. Acceleration is smoother, and it tackles inclines with an ease it hasn't had in ages. It's like my car has found its second wind! ​But what truly sets Gewinnen apart isn't just the immediate performance boost, it's the incredible expertise and care they showed regarding my car's overall health. Not only did they deliver on the performance promise but they also took the time to explain exactly what was contributing to my engine's condition and, more importantly, provided invaluable advice on how to improve its longevity and efficiency. They shared specific tips on what type of engine oil to use and changing spark plugs every 40k etc that I had no idea about. This proactive approach to engine care is something I truly appreciate. ​It's clear that this product isn't just about a quick fix, they genuinely care about helping you maintain your vehicle in the long run. The combination of a noticeable performance improvement and expert guidance on engine maintenance makes this product/service an absolute game-changer. ​If your car is feeling a bit tired and you want to give it a new lease on life while also getting expert advice on how to keep it running smoothly for years to come, look no further than Gewinnen. It's a 5-star experience, hands down!”

“Was skeptical when I first saw it in FB. But I decided to take the leap of faith to try and install this. Got to say this has to be the best decision ever. The Nano Bros (Lionel & Leonard) are both skillful in this area and have extensive knowledge on cars itself. They are not just skilled, they are very helpful and willing to share their knowledge with car owners who may not know outside of P,R,N,D. Haha. After few days of installing, I can totally feel that the car is way lighter than it originally was. Slight press and can feel the acceleration is there. This is dangerous though because you will unknowingly hit 60-70 without even stepping even half of what you used to step. Money very well spent, and once my budget is back in, I think I'm likely going to come back with more stages! Thank you Nano Bros!”

“After installation of 6 stages and 1 week of run in, I just pump in 47 litre petrol with the mileage of 621 km for my CX5 2.0. For a car with 1600 kgs weight can achieved 13.2 km/L (7.5 L/100 km) was fabulous compare to my past 6 month drives with 47 litre petrol with the mileage of 520 km. This is only the mileage improved but not yet mentioned about the power sluggish improve. With this minor calculation, ROI would be around 8 months but it’s come with 7 years warranty. Never try and you will never know and feel. I have tried and feel it with satisfied result.”

“The price you pay for, not only improve performance and much better fuel consumption but lots of knowledge and superb advice from a car enthusiastic that money can’t buy. BE THERE OR BE SQUARE! JUST SIMPLY HIGHLY RECOMMENDED!!!”

“Friendly bros and quick installation. No regrets, after installation of stage 4. Can feel the faster throttle response and smoother acceleration. Enjoying my ride every day now. Thank u, Lionel and Leonard!”

“Thank you to the two bros from Gewinnen who gave me a detailed explanation on how the product works. They went an extra mile to give me valuable suggestions on how I can improve my car performance without compromising the fuel economy. Personally, I am more of a performance guy and their suggestions led me take the car to the next level. I would highly recommend them for anyone that is looking for performance and fuel economy. It's very rare to see these both going hand in hand.”

“Honestly, I was relatively skeptical of the product at first, but in view of the countless numbers of positive reviews Gewinnen had on their FB page, I decided to take a leap of faith and give the 4 Stage installation a shot and I have to say that this is the best decision I have ever made. All I can say is that this modification brought out the hidden potential of my car. The throttle now feels a lot lighter and more responsive. The engine is also now a whole lot quieter. Basically, the driving experience has improved and I have to say that I enjoy driving my car even more now.”

“A last minute arrangement with Lionel and he was kind enough to accommodate. driving a 16 years old Lexus GS300 and although a smooth and decent ride, just felt that it was lacking in the throttle response...went ahead with Stage 4 and immediately after the works, a stark difference in the pickup...no longer sluggish... the overall process was quick and had an enjoyable conversation with both brothers who were a joy and straightforward...Will be taking their advice on some minor servicing to be done will be updating them on the FC in due time...”

“Lionel and Leonard are legit in their product. Install stage 5 and felt immediate response on acceleration. I had half tank on last Sunday when install the product and can last me till today Fri before the top up. Despite the performance i am impressed on the fuel consumption which certainly improve albeit having 2500cc. Worth the $$$, thank you so much to both brothers❤️”

“Saw a lot of positive review on nano ionizer and decided to give it a try. At first I kept thinking that it’s a 50-50 chance of getting a better fc.i decided to give it a try and to my surprise,my fc was so good that I didn’t expect that I’m able to reach those numbers.the guy know his product very well and very knowledgeable.its very addictive as I always wanting to up stage more and more stages 🤣 definitely recommend 💯”

“Saw this ad kept appearing on facebook and decided to give it a try. Did not regret trying as they are friendly and helped me to improve my car’s performance and fuel efficiency and now my car does not feel sluggish in terms of acceleration and also rides has been smoother as well. Highly recommended. I myself even considering going back to them for stage 5.”

“Let me share with you I’m the guy who is very skeptical about this kind of products as I have tried something similar before and it does not work at all. But after seeing so many good reviews, I decided to give it a shot as I felt that my ride does not perform to what it supposed to. *Noted: my car is stock. So I met up with the 2 gentlemen with an open and positive mind. They began to share with me some of the car knowledge, explai… See more”

“I was contemplating about the product until i went over to give it a try. Kid you not, the car turns out like a monster ! Smooth and powerful, i recommend to all drivers to meet our friends here to give it a try ! 😄”

“Seen alot of positive reviews and has been itching to try. In the end decided to go for stage 4. Both Brothers were extremely friendly and ready to share their knowledge. Quick work was done for my car and i can feel the difference the moment i put my foot on the pedal. As im a little sensitive to my drive and pedal response. It was all worth it although during the process i was a beginning to doubt my choice to do it. 🤣 But the moment it was done, and i put my foot to the pedal. i know it was all worth it. FC wise, i believe its slowly adapting? As i can slowly feel my FC getting better. Definitely recommended for car lovers and drivers who wants the best for their car. ⭐⭐⭐⭐⭐”

“Combo Stage 1 to 4: Accelerator-to-Car Pickup improvement (eventhough some engine parts wear-and-tear, eg. Rocker Cover Gasket leakage, Valve Seat Seals in wear-and-tear, oily basic spark plugs; which contributed to engine cold start and in long term rough engine idling below 1,000 rpm). 5th Stage upgrade - Engaged their service again: Sent to authorize car workshop for necessary car parts change with back to its default condition. Brief engine crank as compared before and experienced great fuel efficiency (reset my average fuel consumption per 100km results minimum 18km/l to 20km/l for my SX4 2008).”

“Had a fun and enriching session with Lionel and Leonard. During our discussion, can really feel their passion towards cars. As for the product, I went for stage 4 and it really works. Throttle became more sensitive and FC saving from 9km/l to 18km/l (wtf, I know). For those that are still hesitant, just go and try. Won't regret! Good job guys!!”

“Very skeptical about how the product is, no modification needed to be done and can still save petrol. Tried it out first with the power supply cable installation only 2007 wish able to save from 11.0km/l to 12.4km/l is not much cause i only install one stage but im able to see the guaranteed 5-10% of fuel saving half tank 521.1km no joke. In terms of power, my acceleration have never been smoother, my rev is lower when cruising. Definitely will recommend to my friends.”

“Saw their ad on FB to improve performance and fuel consumption, so i thought why not? Since i planned to use my car for grab, every bit of improvement in fuel consumption matters. However, since this was my first car, i barely knew much about what's normal and what's not. Only when i brought my car to them we realised that my fuel consumption was terrible. It was at 6.3km/L. They laughed when i told them i think it's not bad and followed up with proof of people of the same car (brand and model and of the same year) who actually thought 9.5km/L was bad. That meant mine was way worse! So i requested for the full 5+ stages of the Gewinnen Ionisation. Afterwards they educated me alot on other ways to improve my fuel consumption and what i can do to best take care of my COE car so that it can last the remaining years. Installation of their product was 19 Feb 2023. Now 7 Apr 2023, my fuel consumption is at 9.0km/L! Still bad, compared to the norm...but i am definitely happy and satisfied! That is an increase of 2.7km/L. With a full tank of 60L meant i get to drive an additional of about 160km! I am just really happy, hence this review. If you are reading this, go and try their product, cause all other reviews say the same thing, that it works! Thanks again guys! For the installation of your product and for the free education hahaha! Still waiting for your stickers/decal 🙂”

“These guys really need to be known to all drivers who wish to improve their vehicle performance.. I am so so happy that I went to them toboost my car performance.. My estima have so much more power after the installation.. The pick up and acceleration is so much faster and smoother.. I even need to mention that I cant feel the vibration or sound of engine when im on idle or driving.. I am so impress and what they help with my car.. fuel coonsumption is also much more saving. Guys Dont hesitate anymore . These guys are so so so much recommended.. My honest opinion.. No bluff one.. dun tink twice.. Just goooo... I cant say how much I want to recommend u all but really it is WORTH IT.. I am so much happy with my car performance now. So much more happy I went to them..”

“Highly recommended after installing stage 1+2+3+4. Can straight feel the car is different and no need to accelerate more. The car feels more lighter & torquey. Driving up slope is better. Thanks bros.. 👍”

“Initially did not know much about such technology as not many such services in Singapore. Decided to give this a try, and there was definitely a significant improvement in my acceleration. Previously there was a lag and hesitation, but after this, my acceleration was instantaneous much smoother. Recommend to try at least once to feel the transition. 👍”

“Of course i will give an honest review... So just now after i tried.. acceleration is better... Smoother than i thought it will be.. Power on acceleration is subtle... But can feel the difference.. I understand my car not build for acceleration due to weight and size.. But.. let's skip to the good part.. The mid range and top end is superb!! .. Superfly!... Its banging..! And no more jerky feeling during gear changing at 5000+rpm... Really² much smoother now but with additional power... I was at gear 5 driving at 110km/hr on ECO mode .. hahah thats super super good.. really good... I have not changed my spark plugs yet.. but once i did change i update u again... For the FC i will take note and update u in a week time... Overall i am satisfied and astounding .. really works for my B class...👍🏽👍🏽👍🏽👍🏽👍🏽 good job bros! Thank u for the good service i had.. ⭐⭐⭐⭐⭐”

“Did the stage 1 to 4 and to my surprise, the drive is so smooth that caught me by surprise. Reasonable price and no modification. Highly recommend.”

“Both Lionel and his brother were really forthcoming with information and explanations on their product. It was an absolute joy to deal with them and chat about car mods and dogs. Thank you both for boosting my car. It flies better and more efficient now. 😂 I must be careful of hidden TPs and speed traps now.”

“I've been following this page since their early days but was hesitant to engage them as I was selling the previous car. Finally installed all 4 stages and the two brothers went out of their way to provide additional assistance and information for my car. Initial changes noticed after the installation is the throttle is lighter and the FC kept getting better even in full 100% city drive. So far till date I have achieve an increase in 1.5km/L from the meter readings and actual manual calculation of fuel consumption. The installation is still in the early stages but the immediate improvements is noticeable so far and the process took less than an hour. Lionel and Leonard are super helpful and are well versed with their product and other car related matters. We spent a considerable amount of time discussing parts upgrade, driving dynamics and etc. Thank you Lionel and Leonard, would have engaged you guys earlier if I was not selling the old car.”

“Very Surprise with the end result. instant feel can get the difference. caution to those whom wanna install. "Speeding is an offence"”

“Installed 1-4 stages on my VW CC 2.0 and immediately feel the difference. Car is more responsive and hardly any feel of turbo lag. Able to deliver so much power at lower rpm, that I need to adjust lighter taps on the accelerator to control speed. Fuel consumption drastically improved - on same route before installation 15L/100km, after installation around 10L/100km. Very highly recommended and also the bosses very knowledgeable and friendly, can definitely take their advice for your car.”

“highly recommended did stage 1 to 4 the power can feel the difference and the acceleration and gear change smooth 👍👍”

“highly recommended after trying out the product acceleration and response feel alot smoother and light fuel consumption also improved thanks the 2 bro for this product 👍”

“I driving a Subaru Impreza hutchback just after install stage 1 + 2 and drive from toa payoh drive back to bukit batok the distance was so shot but can already feel the car is different and I no need to accelerate more although I had throttle control..my car feels more lighter and drive up to the MSCP is better.. I will come back for stage 3 n 4. Thanks bros.”

“Im driving a VW Touran 2011 car. I must say the two brothers are very genuine and honest in their installation. Personally test drive my car to ‘feel’ the before and after. Did stage 1+2. Steering wheel was more lighter (surprisingly), up gear and down gear more smooth in the sense car was less jerky, gear change and speed picked up with lower rpm. Will be coming back for 3+4 to see more result after fixing the car health issue first 😅”

“A pair of very knowledgeable brothers that freely dispenses valuable information about your car and how to improve its condition. They are also willing to answer questions and share contacts after the service is completed. Thank you so much, enjoying the speedier drive now.”

“Did stage 4 at one go after recommendation by my friend and also reading up the reviews on their page. Am driving a 2013 MB C180 CGI with a stage 1 ECU tune and the car just feels so alive now after the nano ionisation. These are the following benefits I have experienced : 1. Smoother acceleration and pick up. 2. Greatly improved FC. Used to be able to do 150km - 180km per 1/4 tank but am doing 200km per 1/4 tank now. Based on my fuel tank capacity of 60L , that's 13km/L. Initially it may seem that the benefits are not obvious but it takes some time to stabilise as the ECU takes some time to re learn and adapt. Give it about 1 to 4 weeks depending on the health of your car. Lionel and Leonard are both extremely easy going and friendly and give post sales advise sincerely and you can feel that they only want the best for your ride. It may seem too good to be true that some stickers can improve performance that much but you have to try it to believe. I wouldn't call it magic koyok but its more like a breakthrough technology that would benefit your car and is a great complement to any tuning. I have recommended this to many fellow drivers and would definitely do stage 5 if it's available! Update : 19 Jul 2022. 230km achieved on 1/4 tank ( 13% improvement compared to previous best mileage achieved on 08 Apr 2022 ) Product still doing its magic ! absolutely awesome. 💯 Changes : 1. Added S*P Complete Fuel System Cleaner to S*C 95 after experiencing some loss of power and acceleration.( Did help with restoration but FC didn't change.) 2. Switched to C****X 95 from the usual S*C 95 as advised by Lionel before and that's when I got the current mileage. Conclusion : These 2 bros really know their stuff and their advise is spot on. Try it to believe. See less”

“They are too good to describe. They know their product well. And they also go extra mile to guide me thru the process and recommend thing that will improve my car performance. Awesome Jobs guys👍🏻👍🏻👍🏻 I’m so satisfy with my car now and it’s become like a wild horse running on the road 🐎🐎”

“The product looks simple but it works like magic, improve my horsepower and torque. And best of all fuel saving. Very good products.”

“At first when they explained, I was unsure of these 'camoflage koyoks'. How can these help to improve my car performance? But decided to give it a try on all the 4-steps when I saw the sincerity in them. They even help me with my car and pin-point the problems that I should take car of and we talked like we known each others for years while doing my car🤣. And true enough my car now sliced the road like cake hahha. Smooth ,pick up,gear change are all improved. Thumbs up to both brothers. Highly recommended!!!! Give it a try and u will know what i mean😊”

“Wonderful job done by the 2 brothers. Rlly felt improvement right after product is installed. Gave lots of advice on how to max the potential of the engine. Very highly recommended!”

“Overall I’m really satisfied with their product! After doing all the stages from 1 to 4, I can notice my car is more responsive and lighter. For FC wise definitely a lot better than before. Now I’m driving my car without Eco mode and the FC is better than with Eco mode on previously before I did all the stages. And the 2 brothers are very knowledgeable and professional with their products! Can recommend to others with a peace of mind 👍🏻”

“Both Lionel and Leonard are friendly and very knowledgeable. Just did all 4 stages yesterday. Car is more responsive. Strongly recommended their services.”

“First of all, I don’t usually write a review, but I am keen to write for this “koyok” thingy. I was looking for further engine responsivenss as my car is a non turbo engine and wanted to increase driving experience for fun. To add some histories, my car has upgraded to air speed (closed box) with shorter air intake and installed with XLR racechit. As a results, the car is far responsive as compared to stock. I happened to saw this advertisement about Nano Ionisation in FB and I was just like many others with or without technical knowledge, how some nano tapes can help to improve engine responsiveness and results in fuel saving? It makes no sense right? I laughed loud to be honest, but after reading many reviews, it seems proven. My curiosity booked the next day appointment with full stages (4 stages in a go), I must be crazy for all 4 stages in a go right? but I just wanted to try the max effects since I am spending money already. On the installation day, met Lionel and other gentlemen, they are nice and experience in car performance upgrades. When I saw the tapes, I wanted to laugh again, but I controlled as they look very professional and show 100% confident on their product. To be honest, it is just to paste a few tapes here and there, I can feel how people look at it with strong skeptical. I really didn’t believe it, but I hope it works. After installation, start the car and go for a short sprint within the car park (short distance lah), feel some improvement in engine response, but I tell myself it is just my mindset as I spent money and my mind may leaning to yes, yes, yes very power now…, u know what I mean… But I can’t say no either as I don’t race in a multi story carpark and can’t tell right?😀 so I say goodbye and left for more testing. I know my car well, I know my car’s response in certain speed, gear change and acceleration. Tested for 1 night and 1 day with my regular driving habits and routes, guess what? It actually improved in engine responsiveness and the gear change is faster. Fuel saving will be measured after 1 or 2 tanks, but so far on my regular route to work, I got 15.6km/l as compared to 15.1km/l as before. It really works like magic and I enjoyed very much. This review is purely for my experience sharing, believe it or not, go try and find out yourself. Thanks for reading this lengthy review.”

“The Nano Brothers are AWESOME ! Did up my Stage 4 today and I have to say not only were they professional and efficient thru out the whole process . The advise they gave me about my car was GOLDEN ! I learnt so much from them in that 30 mins . My car now starts up faster and it is so much smoother . Had such a great time and I would definitely recommend this to anyone . Nano bros 4 LIFE ! 🌟🌟🌟🌟🌟”

“Amazing product! I am driving Opel Mokka and my throttle response became more sensitive and my car became smoother & quieter after installation. Fuel savings increased from 18.18km/litre to 20.83km/litre. So I’m finally back on this update again. Stage 4 is really working well Even though I’m on 19” wheels So here what happened . I was having some issues with “ high “ idle rpm Then installed raizin voltage stabiliser. After that awesome wiring work by workshop mech I went to look for “ nano” brothers. Now moving off is very smooth. Here’s a pic of the updated fc. Proven gewinnen is good 🙂”

“Chanced upon their fb page while researching in way to improve my old car’s FC. I believe the reviews speak for itself! Lionel and his brother were not only knowledgeable , they were very engaging and provided feedback from my driving style to good advise. The installation process was smooth and quick, they requested for me to do a test run to ensure all was working well before they let me leave. The level of professionalism and dedication to their work should be testament enough. Will def be back for my new car ! Immediate results include clear throttle response and seen visible improvement on fc ! Good job guys!”

“The mod works well and there is really improvement in performance! I am equally shocked as well! Thank you so much for your kind sharing for car care and maintenance during the installation too. For fuel efficiency, from my initial calculations there are some improvements already, hope there will be more in future! 👍🏻👍🏻 am very impressed how the car react differently just by pasting those "wonderful koyok"! 😋😋”

“Wish 09 2nd Gen Today is my 4th day after installing stage 3 into my car....I know its gonna be a difference but its a matter of time and i dont expect it to be early. On the day itself i can feel slight improvements after installing. The car was with better response during overtaking and taking off but i did not focus much on fuel consumption. 2nd day i only drive for 45km only 2hrs Travelling time..... 3rd day driving for 109km only for 4.5hrs and observed that my car response improves and give me as I demand and also notice that my fuel tank gauge at 3/4 for 316km covered. Normally at this fuel level it can only cover 200km-230km......seeing is believing......I am going to use up my fuel till the fuel reserved lights up and will clock the mileage again .....No regrets Installing.....will meet 2 bros who is good, friendly and knowledgeable .....”

“A bit sceptical about this product. After reading all the positive reviews, decided to try it out. Went straight for full stage 3 installation. Two bros were absolutely friendly and confident about their product. Willing to share a lot invaluable experiences too. Was asked to try the ride after installation. Immediately could feel the car was lighter and more eager to rev. After a few days of driving, I could confirm that the tapes really work! Acceleration is better and the engine is able to rev more freely. Gear change also smoother, making my ride more joyful and confident, especially overtaking at low speed as my ride is heavy. I can say these magical tapes are really best bang for buck! Not forgetting it is one of the safest mod in the market. Highly recommended to those who want to improve their car's responses. Still monitoring the fuel consumption but I am satisfied with the product!”

“just done it really good n value money,no worries u pay first later all u take back,why?I tell you all now before do this nano my old altis full tank 50 run less than 500km,done this nano now second full tank run close to 600km really value for money.”

“To be honest, I was a little skeptical at first about the fuel saving and power increase. However after looking through the review I gave it a try for Stage 1+2+3. Both the brothers were friendly and very confident in their product. After the fix they ask me to go for a test drive. Immediately I felt the difference, at first I thought my mind was playing tricks on me. After awhile I can feel the paddle is lighter and I don’t need to paddle as hard like how I use too. I was finding ways to save fuel and this is definitely the solution to it! From my first full load of fuel I am able to see improvement! Look at the attached pictures 😉 Great work guys!”

“My Attrage is usually quite slow in moving off. I was sceptical about this product. After installating stage 1 and had covered about 15km so far, I can say that the throttle response has improved especially when moving off from stationary. The car felt alive, like having a shot of espresso coffee when you wake up. I will have to monitor on the fc in the next couple of weeks. Overall experience was good, bros were friendly too. For those who seek improvement in performance of their car can try it out, worth it.☺️”

“Had a minor scare when FC went up after installation. but the owners assured me and eventually the FC got better. 50km more for 95 octane fuel (550km to 600km mileage for 3/4 tank) and 80km more for X-Power (600km to 680km mileage for 3/4 tank). Overall, worth it! Not forgetting to mention that they referred me to their mechanic for car maintenance when my workshop messed up and also gave me some tips for car performance matters. Going beyond what is required. 👍 Edit: Clarified on some query and updated the review.”

“I am driving a insignia , recently found this two Brother on Facebook about fuel saving tape and it give me the interest to try it out , at start I tend not to belive Cus is just a few tape sticking on part of the car engine , but after sticking it , and driving it for few days my fuel consumption from 9.8l per 100km Drop to 6.9 per 100km which drastically give me a very good fc after that , and I am surprise to it, so for this tape service I would highly reccomand”

“I am driving an Opel Astra K 1.4T . After applying the tapes, my throttle became more responsive than before. The turbo lag has been reduced as well. Fuel consumption has dropped from 8.5L/100km to 7.5L/100KM Amazing product to help with Fuel consumption and throttle responsiveness.”

“I'm driving a Lexus RX270. 4 cylinders capacity on a large SUV body. Pick up power is normal compromised, especially during overtaking or approaching up slope. Now can feel the diff after installation 2 days ago. The power is there. Engine smoother and quieter. Now monitoring the fuel saving. Worth the investment. Cool!”

“First Honda FC 1.5T to install the tape all stage 3 done. I shall not talk about the comfort of the drive as each to its own. Numbers dun lie on my lufi meter, my air intake increase and stock car's turbo can easily reach 0.4-0.5 boost in a heartbeat ... before that it was quite a struggle. Fuel consumption went down on my drive home will monitor more. Honda Civic fc owners should give it a shot.”

“Just installed on my QashQai 2018. Went full all 3 stages. immediately felt the car, previously rather sluggish bcos 1.2 Turbo, giving way better pickup and responses, even in reverse gear. now i have better confidence to come out from junctions, overtaking etc. FC wise cannot tell yet, but will continue to monitor. Thanks bro for this magical Ko-yoke hahaha... hard to believe they WORK! one word...AWESOME!”

“Done up 3 stages at a go on my Suzuki swift. Could tell the difference, i must say the engine has became more smooth, responsive and silent. Both brothers are very friendly and knowledgeable about their product. Understand that majority of the people might think it might be a hoax but i will attest to it, you will have to see to believe it! Light pedal and you will know difference from before and after. Will continue to monitor the FC since done fresh from the oven”

“Was quite skeptical about this product, but nevertheless decide to give it a try. The results are worth the try. Car is more responsive with increased power, driving becomes smoother with lesser noise. Still testing fuel consumption. Hopefully to see an increase of mileage. The brothers are generous to share every knowledge about cars, even after sales. A good advisor to consult if you wish to mod your car Keep up the good work guys!”

“Did all 3 stages for my mini. Car engine become more smooth , responsive & quiet. Both brothers are very knowledgeable and helpful. Learned a lot from the both of them. Those magical tapes I wish I can tape my whole car. Thank u Guys. Way to go! Will lookout for my fuel consumption though. As I just tape a couple days. Thank you brothers once again!”
