COBB Tuning FMIC BPV Adapter - Subaru Models (inc. 2002-2007 WRX / 2004+ STI)

Better Airflow for the GD WRX/STI — Done Right

The Cobb intake upgrade for the 2002-2007 Subaru WRX/STI improves airflow to the turbocharger over the factory setup by reducing restriction in the intake path. Less restriction means the turbocharger works with a stronger air supply, building boost from a better foundation.

Designed Around the Cobb OTS Maps

Every Cobb intake product for the GD WRX/STI is developed alongside the OTS maps on the Accessport. The intake and the tune are calibrated together — which means the airflow numbers the map assumes are exactly what the Cobb intake delivers. Running a third-party intake against a Cobb map introduces uncertainty; running the Cobb intake removes it.

Bolt-In Installation at the Factory Airbox Location

Installation is at the factory airbox location on the GD WRX/STI — no cutting, no relocation, no custom heat shielding. The Cobb intake system replaces the factory airbox and filter as a unit, and all mounting points line up with factory locations.

About Cobb Tuning

Cobb Tuning has been developing performance parts and tuning solutions for Subaru vehicles since 1999. Based in Austin, Texas, Cobb built their reputation on the Accessport — the most widely used Subaru ECU tuning device on the market — and expanded that into a full ecosystem of intake, exhaust, drivetrain, and engine bay accessories engineered specifically for the platforms they support. Every Cobb product is developed in-house and validated on their own test vehicles before it reaches customers. Subispeed carries the full Cobb catalog because their engineering standards and platform-specific development process consistently produce parts that work exactly as advertised.
