Features
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 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.
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.
I had an AEM intake on before this and what a huge difference. Both in sound and performance. Oh, and the very fast unexpected delivery. Thank you guys from IIR.

very easy to install and great sounding
If you're looking for that louder turbo woosh look no further! COBB products just work awesome! Thank you to Import Image Racing for the great customer service and the fast shipping!
Cobb always provides fine fitment for STi's. The SF+ is no different. The installation is straight forward and if in doubt, go to their website for installation instructions and pics. You must use the Stage 1+ tune after installation via an Accessport unless you get protuned. The car breathes much better and with the removal of the "milk jug," sounds great! I would recommend this over other CAI's.
