The airbox is constructed of black powder coated aluminum. A slot in the front of the airbox accepts air directed through the factory air scoop. Air is filtered through a larger pre-oiled filter and routed to the velocity stack MAF housing. The wire-reinforced black silicone couplers are sealed on either end with clamps for a leak-free install.

Velocity Stack MAF Housing:
This intake system utilizes several unique features in an effort to maintain optimal flow for performance while minimizing turbulence. A custom conical air-filter element, CFD-designed velocity stack and unique air flow straightener grid are designed to smooth the incoming air flow as it passes the Mass Air Flow sensor for precise readings. The one piece high temperature plastic composite design saves weight and reduces heat transfer.

The SF Intake System is compatible with COBB Off The Shelf Maps. Look for maps denoted with "+SF" in your Accessport firmware or on the Maps section of our website. For a complete list of maps for your car, head over to the Maps Section of our website.
