Unlock true Flex Fuel capability with the COBB Ethanol Sensor & Fuel Line Kit, designed as a plug-and-play solution for the 2011–2014 Subaru WRX. This kit serves as the core of the NexGen Flex Fuel system, delivering precise ethanol content readings so your ECU can make real-time adjustments for performance, safety, and reliability.
At the center of the setup is an OE-quality ethanol content sensor mounted to a durable, powder-coated aluminum bracket. Fuel is routed seamlessly through the included pre-assembled fuel lines, each equipped with OEM-style quick disconnects for a secure, leak-free fit. A billet adapter is also included to ensure smooth integration into the factory fuel system.
The result is a fully compatible, clean, and efficient installation that brings accurate ethanol monitoring directly to your ECU — a must-have for anyone running E85, blends, or a full Flex Fuel calibration.
