COBB SF Intake & Airbox for 2015-17 Subaru STI (Black Silicone)
COBB Tuning SF intake and integrated airbox looks great and has the combined benefits of a short ram intake and a cold air intake without any of the negatives. COBB's intake system utilizes several unique features in an effort to maintain optimal flow for performance while minimizing turbulence that can cause engine management problems.
First COBB utilizes a custom conical cloth air-filter element with 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 which eliminates the "dead spots" experienced by other aftermarket intakes due to turbulence. No other aftermarket Subaru intake system utilizes these critical design elements.
Second COBB created a one piece MAFH 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 under-hood heat and in turn heat the incoming air.
Third COBB created the SF Air Box which adds the benefits of a cold air intake to the outstanding performance of the SF Intake. The OE inlet directs cold air from the front grill to the SF Air, which encloses the SF intake. Hot engine bay air that robs horsepower is prevented from entering the intake system. This unique design also separates rainwater from the intake air, eliminating the water ingestion issues that plague in-fender cold air intakes.
Calibrations - All aftermarket intakes for 08+ Subaru's require tuning in order to ensure the MAF sensor reads properly and the engine operates within safe parameters. COBB Tuning has you covered with Off-The-Shelf Maps for the Accessport, making it as easy as install, flash and go!
