The COBB Stage 1+ Big SF Power Package is a complete bolt-on and tuning solution designed to unlock the hidden potential of your 2015+ Subaru WRX. At the core of this package is the industry-leading Accessport V3, the most flexible and user-friendly ECU tuning device available. With preloaded Off-The-Shelf (OTS) maps, the Accessport V3 instantly optimizes your WRX for performance while still maintaining drivability.

To complement the tuning, this package includes the Big SF Intake and Airbox combo, built from 3″ mandrel-bent aluminum tubing finished in black for a clean, OEM-plus look. The intake system is paired with a dual cone green filter and a black powder-coated airbox featuring a laser-etched COBB logo. This setup dramatically improves airflow over stock while keeping intake temperatures stable and consistent.

By combining increased airflow with the tuning capability of the Accessport V3, the Stage 1+ Big SF Package delivers noticeable horsepower and torque gains, improved throttle response, and an aggressive turbo sound that enhances the driving experience. This is the perfect first step into performance upgrades for your WRX.
