COBB Stage 1+ SF Power Package 2015-2021 WRX

Unlock more power and performance from your 2015-2021 Subaru WRX with the COBB Stage 1+ SF Power Package—a simple bolt-on and tuning solution designed to deliver noticeable gains. At the core of this package is the Accessport V3, paired with the high-flow SF Intake and Airbox combo for increased airflow and enhanced engine response.

The airbox is crafted from black powder-coated aluminum and features an opening to capture air from the factory scoop. A larger, pre-oiled air filter feeds into a CFD-designed velocity stack housed in a precision MAF body, ensuring smooth, accurate airflow. Wire-reinforced black silicone couplers and premium clamps guarantee a leak-free seal.

Engineered for both performance and reliability, this intake system includes a custom conical air filter, velocity stack, and an airflow straightener grid to reduce turbulence and ensure precise Mass Air Flow sensor readings. The lightweight, high-temperature plastic composite construction minimizes heat transfer while maximizing efficiency.
