Cobb Tuning SF Intake & SF Airbox - Forester 09-13, WRX & STI 08-13

This C.A.R.B. approved intake (2010+ pending) 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.

This 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 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.

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.

The SF Air Box adds the benefits of a cold air intake to the outstanding performance of the SF Intake. The factory 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+ Subarus 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!

    Intake install

    So I did the intake install myself along with the access port. Everything was very easy with no problems if you have some basic mechanical. Anybody can do it, just take your time. My 2013 WRX Hatchback runs like a scalded cat now! The differe ce that these 2 things made is like night and day. Highly recommended.
