We offer FREE SHIPPING on all Cobb Parts! NEW! - the Cobb SF Intake system is for the 08+ WRX and STi! Cobb's 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, Cobb uses a CFD-designed velocity stack leading to an unique air flow straightener grid. This straightener grid is specifically designed to smooth the incoming air flow as it passes the Mass Air Flow sensor for precise readings. This eliminates the "dead spots" experienced by other aftermarket intakes due to turbulence. NO other aftermarket Subaru intake system utilizes these critical design elements. In order to provide a system that looks as good on the outside as the technical advancements happening on the inside, Cobb utilizes a one piece design constructed from a high temperature plastic composite. Not only does this save weight compared to the previous metal design, the plastic composite material offers much better heat rejection properties that help keep intake air temperatures cooler. In contrast, intake systems constructed using metal castings or piping can actually retain underhood heat and in turn heat the incoming air. Tuning is required for this intake! If you have an Accessport, Cobb does have pre-built maps available at this link. Intake ONLY
