Cobb 08-11 WRX/STi Black SF Intake & Air Box Combo

Description Cobb SF Intake & Air Box This is COBB’s SF intake system that is C.A.R.B. certified for the 2008-2014 models. The SF intake utilizes COBB’s custom design that maintains optimal flow while minimizing turbulence around the MAF sensor. This design provides the most consistent airflow measurements under all driving conditions and delivers an audible turbo spool sound under full throttle that will make any enthusiast smile. For you techies, this 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 our motor by a heated intake charge. Note: The COBB Tuning SF Intake system for the 2008 models requires use of specific OTS (off the shelf mapping) provided for their Accessport ECU tuning device. For the best results we highly recommend a custom E-tune aka Pro tune.
