The C.A.R.B. certified COBB Tuning SF Intake for the EVO X utilizes our own unique design that provides smooth air flow to the turbocharger. When installed on a stock EVO X, our SF Intake system frees up an additional 21 HP and 24 lb-ft of torque to the wheels. Expect even larger gains when running higher than stock boost levels. Simple to install, this is great first step in your quest for more performance.
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. In order to provide a system that looks as good on the outside as the technical advancements happening on the inside, they 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.
