The TGK Motorsport flex fuel kit is a plug and play solution to adding flex fuel on Audi 4.0T Vehicles. Use of this kit is to add the ability to run anywhere from straight gasoline to E85 Blend as well as reveal the true power potential of your setup.
Forced induction scenarios especially benefit from the use of ethanol, and these allow you to seamlessly switch between gasoline and ethanol without having to monitor your fuel content or reflash your tune.
