Cobb Flex Fuel Complete Package 2004-2007 STI, 2006-2007 WRX

  • Harness the power of ethanol, while maintaining ease of ownership and the flexibility to fuel up where and when you want. Flex Fuel is a combination of hardware and software that will allow your car to run on any mixture of gasoline and E85 fuel. A fuel pressure sensor and ethanol content sensor will deliver fuel quality information back to the ECU, where it will adjust boost, fuel, and timing parameters accordingly. It's a whole new world of high performance.

    The Cobb Flex Fuel Complete Package includes an ethanol sensor as well as a fuel pressure sensor. Utilizing COBB custom features along with this package, both fuel pressure and ethanol content values are able to be sent to the ECU and monitored via custom Accessport Monitors.

    Flex Fuel implementation requires custom ECU tuning. Do not even THINK of installing this kit without custom tuning!

    Note that we recommend a MINIMUM injector size of 1000cc for Flex Fuel implementation, and a fuel pump upgrade is REQUIRED.

    Fits all 2004-2007 STI, and 2006-2007 WRX. Note that 2007 STI has a special electrical plug; specify your model year.
