Cobb Tuning [08-14 WRX, 08-21 STI] Previous Ethanol Sensor to NexGen Flex Fuel Upgrade – Module + Harness Only

The COBB Previous Ethanol Sensor to NexGen Flex Fuel Upgrade Kit adds the NexGen Flex Fuel Module and plug-and-play harness to a vehicle that already has the previous COBB Flex Fuel system installed. It supports the ECUs use of ethanol-content data through an Accessport-delivered NexGen Flex Fuel calibration.

Fits 2008-2014 Subaru WRX and 2008-2021 Subaru STI, including 2015-2021 WRX STI, with supported USDM manual applications.
Includes the NexGen Flex Fuel Module and harness only; an existing previous Flex Fuel system is required.
Mounts to the passenger-side strut tower and processes ethanol-content data for the ECU.
Uses OE-quality connectors and plug-and-play wiring for the existing ethanol sensor.
2008 WRX vehicles require custom tuning because OTS maps are not available.
California sale or use on emission-controlled vehicles is excluded while CARB testing is pending.
