Flex Fuel kit – Subaru WRX & STi 315600



Update 3/16/22: The Cobb Flex Fuel kit for WRX FA20 has been discontinued. If you need to add a flex fuel sensor input to your Subaru we have exactly what you need: VE Flex Fuel sensor kit + subaru TGV connector + 0-5v signal converter here. These are all the parts you will need to add flex fuel data to your OEM Subaru ECU. The VE flex fuel kit also comes complete with -6an inlet/outlet fittings on the flex sensor for a clean race car spec install perfect for those running aftermarket fuel rails and fuel lines.

Cobb Flex Fuel kit 315600 for the Subaru 08-14 WRX and 08-20 STI means you can now safely run any blend of ethanol/gasoline and your ECU will know exactly how to handle the blended fuel. A custom Flex Fuel E-tune + this Cobb F.F. kit is the best way to get your Subaru running right on pump gas, E95 and every blend between including E85 or whatever ethanol % is available in your area. **Cobb Flex Fuel kits are NOT CARB approved parts. These kits are for off road Motorsports use ONLY.**
