Netting + 11 HP and + 16 lb. ft. gain, the COBB Tuning SF Intake utilizes their custom CFD design to maintain optimal flow and generate ideal performance. The OEM MazdaSpeed airbox is the most restrictive stock intake they have seen to date. Simply replacing it with the COBB Intake will allow your MazdaSpeed3 safe and consistent power gains!

The custom conical cloth filter feeds filtered air directly to the engine, while maintaining optimal intake velocity and minimizing turbulence found with many aftermarket intake systems.

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, they use 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 MazdaSpeed 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. The plastic composite material offers 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.
