E85 Conversion Kits Can Increase Your Horsepower by 12%
The 2001 to 2002 Camaro Z28 is a sought-after piece of machinery that comes with a practically bulletproof 5.7L V8. This rare combination of power, reliability, and fuel efficiency made it a very popular pony car in the United States as well as abroad. Now you can convert this muscle car to E85 with a plug n’ play eFlexFuel kit and experience greater power and lower costs at the pump.
Our eFlexPlus and eFlexPro are plug n’ play E85 conversion kits that come with easy DIY installation instructions. In an afternoon, you can increase your horsepower by up to 12% and start tuning your car for performance. Both kits allow you to run any mixture of E85 and gasoline that you desire. But the eFlexPro comes with an eFlexTuner tuning software that allows you to tune your engine with fuel mixtures above E50.
Installation
