The stock fuel system of your vehicle lacks the flow capacity to run full E85.
You can’t run full E85 and need to blend it with gas. Our app lets you monitor the fuel blend and gives a warning when the limits of the injectors are reached.
If you already have replaced the fuel injectors please list the modifications on the checkout page. Our technical support will then confirm the injector connectors and verify that there's enough flow capacity for E85.

This kit was incredibly easy to install, epic customer service and the improvements to my vehicle from e85 use are awesome. My truck is full bolt ons and has a healthy cam in it. The power is more linear now, it pulls harder and in general runs smoother. Awesome company, awsome product and i cant wait to see what i can do with my next engine set up!Alexander Henkhaus starstarstarstarstar
The guys over at eflex fuel are extremely helpful and make sure you have what you need to complete your set up and make sure your vehicle will function properly. I forgot to mention some items in my fuel setup before placing my order and they Called me to make sure I had or was planning to get what I needed prior to installing the kit for it the function properly. They also explained how to go about working around my tune for my turbo build. I would recommend this company to anyone. 10/10 service and quality products!Nick Krall starstarstarstarstar
Installed their kit on my ram 1500 5.7 and works great. Took me less than an hour to install and haven’t had any issues. Would definitely recommend.Christian Nunez starstarstarstarstar
Can be installed in around two hours. Love the app where you can watch each injector and the ethanol percentage in your fuel. Also, like the ability to change the setting from economy to towing with the app. I haven't used the sport setting yet, looking forward to trying it out soon.Jerry Cordell starstarstarstarstar
The horse power increase alone makes the eflexfuel a excellent investment & I'm paying almost 1/2 less in fuel costs. I highly recommend it! They also have great customer support.Tony starstarstarstarstar
Works great and saving tons of money now that gas prices are skyrocketing.Mateo starstarstarstarstar
Having eFlexFuel on my car has been a gamechanger! I am saving money every time at the pump. The best part is that I can still fill up with unleaded fuel if I am in a place that doesn't have e85. Also, I now own the eFlexFuel technology and when it times to get a new car I can transfer the computer that car and continue to save money. I am very happy with my investment and looking forward to continuing to save.Reed starstarstarstarstar
I was fortunate enough to be in the right place and right time. I got my flex fuel module installed in my gas guzzling 2007 Toyota FJ Cruiser which could only take premium. I didn’t drive it as much as i wanted too because of the gas prices. Now that it’s installed i can run Flex Fuel and enjoy this FJ even more. The guys installed it in a short time and we went on a test drive and they showed me how to adjust the performance with the app and i couldn’t be happier. Thank you so much everyone that was involved and a big thanks to Camille.Ben Benavente starstarstarstarstar
The kit works great on my 2008 eclipse GS, I've had it installed for about a month now running e85 and haven't ran into any problems. When I first tried the install I messed up injector polarity and they were nice enough to offer a coupon code for a replacement wiring harness.Brady Zajac starstarstarstarstar
The kit works GREAT & the support team really help out to make sure it gets done correctlyBryant Choi starstarstarstarstar
Amazing customer support well detailed manual if you read it right the first time I did not but customer service was fully understood my question and replied within a day install was super easy and I do knoticed more power on a naturally asperated v6 3.0 well worth the cash with the price jump in gas.Hunter Turk starstarstarstarstar
Awesome product!!! I installed it on my great condition 2003 Dodge Ram 1500 It gave me more power and cheaper gas!! What more can you ask for. Super fast shipping.starstarstarstarstar
First bought an eFlexFuel kit and converted my Jeep WK hemi. Worked perfectly why I now bought an additional conversion eFlexFuel kit for my Jeep Wrangler TJ and this also works great.Per L starstarstarstarstar
The best e85 module I have tried yet. It does everything they said it would do. Very easy to install, although a couple of the injector plugs they sent wouldn't retain the pins from the module and when you try to plug them into the harness the pins would back out so you had to actually hold the back of the wires into the plugs while you were plugging into the harness. Other than that I am impressed, they really did their homework on this and would buy another for my next e85 vehicle project.Christopher Sayer starstarstarstarstar
I installed on kit on my wife's SUV and was impressed with the low end grunt and greater horsepower that comes with the eFlexFuel product. Bought another SUV and got the same result. Plug and play. The mileage drop is more than offset by the $$$ I'm saving buying 100 octane fuel at $2.59 per gallon.I installed two kits starstarstarstarstar
The eflexfuel kit is very easy to plug and play. The eflexfuel team also has outstanding customer service If you have any questions or conserns. I got this kit in the first place for the performance benefits mainly, but I have found it to be cheaper to run e85 in California vs 91 octane which is about $4.60 a gallon right now. I love the performance, the price, and e85 is a carbon neutral and renewable fuel source which is great for the environment. Definitely worth the money, it pays for it self with the money you save on gas.Samuel Williams starstarstarstarstar
Easy to install and works great. Customer service was great with the questions I had. I'll recommend it.B Prasad starstarstarstarstar
Great response time through Instagram. Much easier install than anticipated. My car has a little extra pep and it’s step.Joseph Pacheco starstarstarstarstar
Recently purchased the Plus kit to install onto my SRT Challenger. I immediately feel the difference in performance power when cycling through the different driving modes. One of the best part of the kit is being able to fill up for way less with e85, especially with the increase of these gas prices. Thanks again guys for all your help.Dean Morales starstarstarstarstar
This would be my second experience with eFlexFuel and it's been great. The products are well built and their customer service is great. I was contacted by one of their associates through Instagram and it's great to know that there's that personal connection to customers. My vehicles run great and I'm proud to post (which I have) and tag eFlexFuel for the great product they put out.Michael Lealamanua starstarstarstarstar
