Description

The NexGen Flex Fuel Module & Harness Kit delivers precision ethanol content monitoring for your 2008–2021 Subaru STI, ensuring peak engine performance with every fuel blend. Engineered to work in tandem with your Accessport-delivered NexGen Flex Fuel calibration, this module delivers real-time fuel composition data to your ECU—so your tune always matches your ethanol content.

Mounted cleanly on the passenger-side strut tower, the NexGen module provides a reliable, efficient solution for flex fuel integration. The included plug-and-play harness connects directly to your existing ethanol content sensor, eliminating the need for splicing or wiring guesswork. Featuring OE-spec connectors and high-quality automotive-grade wiring, installation is fast, clean, and worry-free.

This kit is intended for those who already have a previous-generation Flex Fuel setup and are upgrading to a NexGen-based system. If you’re transitioning to the NexGen Stage 2+ Flex Fuel Power Package, this Module & Harness ONLY bundle provides the necessary components without needing to replace your existing sensor.
