Cobb NexGen Stage 2+ Flex Fuel Redline Carbon Fiber Power Package with AccessPort V3 2015-2021 STI

New! This comprehensive power package provides even higher performance from your 2015-2021 Subaru WRX STI while meeting the EPA’s anti-tampering standards. 

Cobb’s NexGen program aims to re-establish a modification and upgrade path for vehicles that are impacted by tightening emissions standards that prohibit removal of the stock downpipe. NexGen packages are designed to provide similar performance to older Stage 2 packages, while maintaining emissions compliance. 

The NexGen Stage2+ Flex Fuel Redline Carbon Fiber Power Package takes the foundation of the NexGen Stage 2 Redline Carbon Fiber Power Package, then adds the incredible ability to run any combination of premium gasoline OR E85 ethanol fuel. The added octane benefits of E85 allow for massive gains in horsepower and torque.
