COBB Subaru Previous Ethanol Sensor Kit to NexGen Flex Fuel Ethanol Sensor Kit Upgrade (Module + Harness Only) STI 2015-2021

The NexGen Flex Fuel Module is mounted to the passenger side strut tower and handles all of the data processing before sending ethanol content to the ECU to be used by an Accessport-delivered NexGen Flex Fuel calibration.

Tying your existing Ethanol Content Sensor to our NexGen Flex Fuel Module is a custom, easy to install, plug-and-play wiring harness. Utilizing OE quality wiring and connectors makes adding NexGen Flex Fuel on your supported Subaru both quick and reliable.
  
This NexGen Flex Fuel Module and Harness ONLY kit is intended to be used for customers who have our previous implementation of Flex Fuel installed and do not need a new ethanol content sensor in order to convert to a NexGen Stage 2+Flex Fuel Power Package configuration.
