COBB Tuning SF Intake & SF Air Box Package - WRX/STi

The COBB Tuning SF Intake utilizes our custom design to maintain optimal flow and net the ideal performance while remaining unedited from the factory velocity stack. 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 SF Intake system is compatible with Stage 1 and Stage 2 OTS (off the shelf mapping) provided for our AccessPORT ecu tuning device.

Our 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.

The COBB Tuning SF Air Box was designed to capture the cool air supplied to the SF Intake through the factory intake snorkle. Constructed of 16 ga. Aluminum the heat shield consists of a one piece surround, directional lid, and stainless fasteners that help reduce a loss of power that could be robbed from your motor by a heated intake charge.
