Cobb SF Intake With Air Box 2008-2014 WRX/STI

The Cobb SF intake sets the standard for MAF-style intakes with a velocity stack, airflow straighteners and composite body for ultimate performance. 

Increased Power
The C.A.R.B certified (50-state legal!) COBB Tuning SF Intake removes a pre-turbo restriction in the stock intake system. The SF Intake 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, a CFD-designed velocity stack leads to an unique air flow straightener grid designed to smooth the incoming air flow as it passes the Mass Air Flow sensor for precise readings. The intake utilizes a one piece design constructed from a high temperature plastic composite, saving weight and reducing heat transfer.  The Cobb SF air box further isolates the intake from hot under-hood air to maximize power and minimize heat soak.

Increased Induction Sound
Enjoy the increased snarl from your engine and hear the turbo spool more clearly with the addition of the COBB Tuning SF Intake system. Turbocharger induction noise and bypass valve venting sound is much more audible using this intake system.

Easy to Install
The COBB Tuning SF Intake was designed to be easy to install without having to modify your car. Installation requires no cutting or trimming of any components and can be completed with simple hand tools. Simply remove the stock airbox and bolt the SF intake into place in just minutes.

Calibrations
All aftermarket intakes for 2008+ Subarus require tuning, regardless of manufacturer, 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!
