 We've
redesigned our popular SF Intake for the Subaru Impreza,
WRX, WRX STi, and Forester XT models.
The 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 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.
The new second generation SF Intake is a one piece design
constructed from a high temperature plastic composite
material. 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 under hood heat and in turn heat the
incoming air.
Critical for proper air flow management, the COBB SF Intake
utilizes integrated air flow straightening vanes and a
velocity stack so the factory Mass Air Flow (MAF) Sensor can
always measure accurately. Due to these and other
attention to detail features, the COBB SF Intake will not
cause your engine to run lean and is safe to be used with
standard AccessPORT maps.
A powder coated black support bracket is included for secure installation.
