The C.A.R.B. certified COBB Tuning SF Intake for the Subaru WRX / STI utilizes COBB's custom design to maintain optimal flow while minimizing turbulence found with many aftermarket intake systems. This configuration provides the most consistent power for everyday use while at the same time allowing some audible performance feedback!
The COBB Tuning SF Air Box was developed to capture the cool air supplied to the SF Intake through the factory intake snorkel. Constructed of 16 ga. Aluminum, the heat shield consists of a one piece surround, directional lid, and stainless fasteners that help reduce a loss of power that could be robbed from your motor by a heated intake charge.
Note: 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.
