The TGK Motorsport D4 Flex fuel kit is a plug and play solution to adding flex fuel on Audi D4 A8/S8 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.
This kit uses:
- Continental Flex Fuel sensor.
- Sensor Bracket to mount the sensor.
- Plug and Play wiring harness made with OEM connectors and terminals crimped with OEM tooling, as well as resistor inline already preinstalled. Harness also has a secondary output if you want to add a secondary ethanol content gauge.
- PFTE Lined braided lines
- All brackets included for install.
- GT150 Terminal already installed.
PLEASE NOTE: It is possible to install this kit without tuning, but to gain the most out of the kit, as well as to automatically mix blends, the kit and harness is mainly setup to use Dyno Spectrum Tuning DS1.
