Cobb Stage 2+ NexGen Flex Fuel Power Package Blue Subaru WRX 2011-2014 | SUB003NG2S2FF-BL

Product Fitment: 

2011-2014 Subaru WRX

For Subaru enthusiasts looking to go all‑in on ethanol performance, the NexGen Stage 2 Flex Fuel Power Package delivers a complete upgrade path. Developed by COBB Tuning, this carefully engineered bundle includes everything from upgraded intakes and injectors to ethanol content and fuel pressure sensors, enabling your vehicle to safely support and gain from E85 or high‑ethanol blends.

Key Features:

• Ethanol content sensor and fuel pressure sensor kit included for safe mixture monitoring.

• High‑flow fuel pump, large capacity injectors, and upgraded fuel rail/line hardware to support significantly increased fuel demand.

• Performance intake and turbo inlet upgrades to enhance airflow and complement the flex fuel capability.

• Comprehensive calibration support (via COBB’s Accessport) for ethanol and pump gas blends to maximize power while maintaining reliability.

• Designed to accommodate the octane and fuel cooling benefits of E85, enabling more aggressive ignition timing and boost.

• Developed for turbocharged Subaru boxer engines where fuel delivery and mixture accuracy become critical at higher power levels.

Why Choose This Package?
If you’re building a high‑performance Subaru and want the flexibility to run E85 (or blends) while tuning for maximum gains, this package puts all the required hardware and calibration tools in one bundle—eliminating guesswork, reducing mismatch risk, and setting your build up for higher output and safer tuning. By upgrading the fuel system, sensors, and calibration in concert, you gain both performance and reliability.

Fitment & Eligibility Notes:

• Intended for Subaru models with turbocharged engines where flex fuel is feasible—check year, engine code, and existing modifications.

• Requires tuning; installing hardware alone is insufficient to realize the full benefit or ensure safe operation.

• Be aware of emissions and legal restrictions in your region—some states may restrict modifications involving fuel system or emissions‑critical components.
