The C.A.R.B. certified COBB Tuning SF Intake utilizes our custom design to optimize flow for ideal performance. 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.
The Cobb Tuning 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, we 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 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, we utilize 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.
***NOTE***
The COBB Tuning SF Intake system for the 2008+ STI requires use of specific OTS (off the shelf mapping) provided for our AccessPORT ecu tuning device.
