COBB Short Ram SF Intake System Blue 2008-2014 WRX / 2008-2021 STI / 2009-2013 Forester XT

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 Tuning SF Intake system for the 2008+ WRX/STI requires use of specific OTS (off the shelf mapping) provided for their AccessPORT ecu tuning device.
