Cobb NexGen Flex Fuel Upgrade + Fuel Pressure Kit Subaru WRX 2011-2014 | NEXGENFF002

Product Fitment: 

2011-2014 Subaru WRX 

Take full control of your fuel system and embrace high‑ethanol performance with the COBB NexGen Flex Fuel Upgrade + Fuel Pressure Kit for the WRX 2011‑2014. Specifically developed for Subaru’s turbocharged boxer engines, this comprehensive kit integrates an ethanol content sensor, fuel pressure sensor, wiring harness, and dedicated module—everything required to reliably switch between gasoline and E85 or manage higher‑performance demands.

Key Features:

• Ethanol Content Sensor & powder‑coated aluminum bracket for secure mounting and accurate measurement of fuel mix.

• Fuel Pressure Sensor (0‑100 PSI) including billet adapter and quick‑connect fittings to integrate seamlessly with the existing fuel rail system.

• NexGen Module with plug‑and‑play wiring harness built to factory‑style standards, enabling ECU calibration to use the ethanol and pressure data.

• Supports COBB Accessport OTS (Off The Shelf) maps or custom tuning paths to leverage ethanol’s higher octane for power gains. 

• Includes emissions‑compliance notice: legal in many states under the EPA Anti‑Tampering Policy; not legal for sale or use in California until 50‑state certification is obtained.

If you're building for performance, consider running E85 (which has higher octane and often lower cost) or simply want more robust fuel system monitoring, this kit is the next step. By adding both ethanol content sensing and proper fuel pressure measurement you reduce risk of knock, mis‑fueling, or inadequate fueling under boost. It’s especially valuable for turbocharged Subarus where fuel demand rises quickly. The kit’s comprehensive nature ensures you’re covered both in hardware and calibration support.
