Before leaving this review, I used the Ecofuelbox Pro+ kit on my car (Citroën C4 1.6 110ch) for 10 months to see how it would perform with this kit in summer and especially in cold weather. Now, based on my experience, I can confirm - everything works perfectly well.

In my opinion, the Ecofuelbox Pro+ is the best E85 ethanol conversion kit on the market. Moreover, it's the only kit compatible with HEMI engines. I received my order in 24 hours. It's easy to install and works perfectly on my 2011 Chrysler 300C 6.1 HEMI SRT-8. Communication with the technical service was very quick and pleasant.

The UPS delivery took longer than expected. By carefully following the user manual, it took my husband about half an hour to install the kit on our 2011 Peugeot 307. We are now running on 100% ethanol, and the car starts even when cold, with just about 1-2 seconds more cranking than usual. Filling up for around thirty euros is amazing!

I bought the Ecofuel box ethanol kit for my 2012 Peugeot 207 1.4l and I am very pleased with the results! Since I started using ethanol, I have managed to save about 50% on my fuel costs. The car starts even better with the kit, and the product quality is excellent. I highly recommend this kit.

Over 12,000 km driven. Works very well. No issues with cold starts, unlike another brand's kit I had previously, which caused the car to start and then stall at least 2-3 times. With Ethanol Flex E85, no such problems occur. I have no doubt that the temperature sensor integrated into the box works well. The quality of the kit is really good. It's a genuine "made in France" product, which is rare to find these days. The quality/price ratio is unbeatable. It pays for itself very quickly.

Works well on my 2002 Toyota Yaris 1.6 vvti. I run it on 100% ethanol E85. The installation wasn't very complex and was done by a friend who recommended ecofuelbox, taking just 30 minutes.

It's been 3 months now that I've been running on E85 with my 2010 Alfa Romeo 147 1.6 Twin Spark, and there have been no issues and significant savings! There's a slight increase in fuel consumption of about 10%, but it's more than compensated for at the pump. Excellent customer service.

I installed the kit on my Volkswagen Golf VI 1.4l from 2011 in August 2022 and I am very satisfied. The installation was easy thanks to the clear and complete user manual. As advertised on the website, I save about 50-55% on fuel costs by using ethanol with this kit. It's surprising that not everyone knows about ethanol and its benefits for the wallet and the environment. Thank you EcoFuelBox for your quality product!

Good quality. Starts with a quarter turn, regardless of the weather. My 2020 Renault Clio 0.9 TCe runs without any problems, just like when I was using gasoline, but I definitely notice the difference at the pump! A full tank for 32€ instead of 85€!

The EcoFuelBox Pro+ kit convinced me from the first days of use on my old 2004 Jaguar X-Type, which has regained a second youth thanks to it. My fuel costs have dropped by more than 50%, and my car runs as if it just came off the assembly line. If you're looking to save money while being environmentally friendly, go ahead and buy this product. I'm sure you won't regret it, just like me. Thanks to Alex from customer service for his valuable advice.

Perfect! High-quality material. I'm not much of a DIY person, so I had it installed on my 2012 Land Rover Freelander 3.2L V6 by my mechanic for 95€ in labor. I've driven 12,800 km since the installation, and the kit works perfectly without any issues. As expected, there's a slight increase in fuel consumption of about 10%.

Excellent product!!!! I installed it on a 2015 Suzuki Swift 1.2, and so far, no issues. I've been running on 100% bioethanol for 5,100 kilometers with no problems. During the order, I made a mistake and selected Denso connectors instead of the Toyota connectors used on my car. I was contacted by the after-sales service, and the correction was made within 15 minutes. The product arrived well-packaged and works very well.

My very first “Made in France” product. Delivered by DHL to the States within 48 hours as promised. I'm an electronics engineer and I have to say - great job guys! PCB looks fantastic! I have tested/used many ethanol kits and EcoFuelBox Pro is the only kit that uses AEQ-100 components and the ORIGINAL GM Flex Fuel sensor. The firmware definitely witten with machine learning algorithms! SInce the installation, kit working like a charm with no hassle and no adjustments on my Chevy Camaro 3.6L. FYI, here in Minnesota, E85 is $3.15 per gallon.

I installed the EcoFuelBox Pro+ kit on my Ford Mustang 5.0 V8 in December 2021 and am very pleased with the results. Installation took me almost an hour. The engine runs great with aproximatevely 5% of gain in power (because of the E85). Here in Sweden winters are quite cold, but I haven't experienced cold start issues with this kit. After-sales team was very kind and professional and helped me a lot during the installation process..

The Ecofuelbox ethanol kit has allowed me to achieve significant savings on my fuel costs. My 2014 Ford Focus SW III 1.6 runs perfectly with the kit, and I've seen a reduction in my expenses of over 50%. I highly recommend this product to anyone looking to save money while driving cleanly.

Excellent product and excellent customer service. I installed the Ecofuelbox kit on my Mazda RX8 (Wankel engine) at the end of January 2022, and I am very happy with my choice. My car runs perfectly on ethanol in winter and summer. During the installation, I needed help, so I contacted customer service and received very relevant and wise advice, bravo!!!

This is not the first Ecofuebox kit I have purchased because I am very satisfied with them. I installed them on a 2014 Chevrolet Orlando 1.8 and a 2017 Fiat Tipo II 1.6 without any difficulty. No operational issues to report after tens of thousands of kilometers combined. Cold starts are handled very well. In short, I highly recommend this equipment.

Excellent contact with customer service and a very high-quality bioethanol kit (connectors, wiring harness, unit). The installation manual is clear and guides you through the installation process. I highly recommend it.

Installed on a Dodge RAM 1500. This is the second kit I have purchased. The first kit (4-cylinder) was installed on a 2009 Ford Focus and runs like clockwork. The after-sales service is responsive. I needed advice for installing the kit, and Alex from technical support helped me over the phone to troubleshoot the issue I had.

In the 10 months since installation, I've driven nearly 9,800 km on my 2007 Citroën C5 2.0i and I am very satisfied. I used to pay over 100€ for a tank of gasoline. Now, I only pay 42 euros for a tank of ethanol (Super U station). According to my calculations, I've already saved about 950 euros! As for the engine, I feel the increase in power and the engine runs more quietly.

I received the package on time. The kit is of high quality and the customer service is excellent. I accidentally broke a male connector while trying to reverse the polarity by pulling the wires forcefully :( I contacted customer service and they sent me two connectors for free! After replacing the connector, the kit works perfectly on my 2010 Fiat Grande Punto 1.4 T-jet. I highly recommend it without hesitation!!

I installed a kit on my Dacia Sandero 0.9L 3-cylinder with Denso connectors. The manual is very explicit; there's nothing to complain about in that regard. The installation is very easy, it's almost plug and play. You just need to test the polarity of the connectors with the provided LED tester. No issues with cold starts. My car starts with a quarter turn. Filling up at 0.65€ per liter is a joy!

My order was shipped the same day!! The delivery is very fast, and everything is very well packaged. All necessary installation materials are included. In 1 hour and 30 minutes, the kit is installed and works perfectly on my 2015 Opel Meriva 1.4. An excellent experience. I will definitely install the same kit on my mother's car.

I installed it on my 2009 Mégane III 1.6i gasoline in just under an hour. On ethanol, the car has more power and torque than with 98 gasoline, which is incredible! The price difference between a tank of gasoline and ethanol is astonishing!

The product matches the description and is easy to install. It took me about 45 minutes to install. The car runs on 100% bioethanol with no issues, just remember to replace the fuel filter after 1,000 km.

I live in a rural area and need to drive to work every day. After the increase in gasoline prices, my fuel expenses became an unbearable burden. My colleagues advised me to install the Ecofuelbox kit to be able to run on ethanol. After confirming the compatibility of my 2017 Opel Mokka 1.4 with the Ecofuelbox customer service, I ordered the kit (delivered in 48 hours). It was installed by the local mechanic in an hour, and since then, I've driven 8,700 km on ethanol and saved about 930€!! Thank you, Ecofuelbox!

Very high-quality kit. Works perfectly, good responsiveness. Comes with all the quick-connect fittings for the injector rail (of various diameters) and a 60cm long fuel hose. I highly recommend it!

Despite a mistake on my part (I chose the wrong type of connector when ordering), the exchange was done very quickly and without additional fees. The customer service is truly top-notch! The kit works perfectly.

I've been installing EcoFuelBox PRO+ kits on my clients' cars for nearly two years now, and I must say that I am very pleased to work with such a reliable partner as Artline International. Top-notch customer service and the quality/price ratio of the PRO+ kits is undeniable.

I installed the unit on a 2007 Mini II One 1.4. The installation was not very easy on this engine. With 100% ethanol, the kit works perfectly without any adjustments. It's just 1-2 seconds longer to start in cold weather. Probably, the temperature sensor should be placed directly on the engine. I attached it to the large cooling hose. No dashboard warning lights are on. The unit is of good quality.

Installed on a Jeep Renegade 1.6 e-Torq S&S. The installation on this engine is not difficult because the injectors are easily accessible without disassembly. You just need to temporarily remove the engine cover to access the injectors. The engine starts without any problems in cold weather at an outside temperature of -15°C. The engine's operation is identical to a full tank of SP 98/E10, with just a slight increase in fuel consumption of about 10%. No issues with power or anything else. The user manual is very detailed (30 pages) with color photos and illustrations.
