COBB Tuning SF Intakes - WRX & STI 2008-2014 - Impreza 2.5 GT 2009-2010 - Forester XT 2009-2013

Setting the standard for MAF style intakes with a velocity stack, airflow straighteners, and composite body for ultimate performance.

All aftermarket intakes for 08+ Subarus require tuning, regardless of manufacturer, in order to ensure the MAF sensor reads properly and the engine operates within safe parameters.

Please note: Airbox Does NOT fit 2015 STI models

The C.A.R.B. certified COBB Tuning SF Intake utilizes a 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 SF Intake 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 a 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.
