Cobb SF Intake with Air Box 2002-2007 WRX/STI

The Cobb SF intake sets the standard for MAF-style intakes with a velocity stack, airflow straighteners and composite body for ultimate performance.  Increased PowerThe COBB Tuning SF Intake removes a pre-turbo restriction in the stock intake system. The SF Intake intake system utilizes several unique features in an effort to maintain optimal flow for performance while minimizing turbulence that can cause engine management problems. From a custom conical cloth air-filter element, a CFD-designed velocity stack leads to an unique air flow straightener grid designed to smooth the incoming air flow as it passes the Mass Air Flow sensor for precise readings. The intake utilizes a one piece design constructed from a high temperature plastic composite, saving weight and reducing heat transfer.  The Cobb SF air box further isolates the intake from hot under-hood air to maximize power and minimize heat soak.
