COBB Subaru Flex Fuel Ethanol Sensor Kit (5 Pin) LGT 2010-2012


Center an Image using text align center

A complete plug and play solution enabling users to convert their supported Subaru Legacy to a Flex Fuel configuration without losing factory compensations. This is the easiest to use and most sophisticated Flex Fuel kit on the market. Utilizing OEM fuel and electronic connectors, the Ethanol Sensor Kit measures the ethanol content of fuel being fed to the motor. That data is then converted into a signal that the ECU can use for adjusting calibrations and to be displayed on a custom Accessport monitor.

Requires custom tuning. Contact DRP for a custom Flex Fuel tune.
