Cobb SF Short Ram Intake Blue Subaru WRX 2008-2014 / STI 2008-2019 / Forester XT 2009-2013
Cobb's SF STI Intake system utilizes several unique features in an effort to maintain optimal flow for performance while minimizing turbulence that can cause engine management problems. Cobb's straightener grid is specifically designed to smooth the incoming air flow as it passes the Mass Air Flow (MAF) sensor for precise readings. This eliminates the "dead spots" caused by intake turbulence.
In order to provide a STI intake system that looks as good as it functions, Cobb utilized a one-piece plastic high-temperature composite plastic body. Not only does this save weight, it also prevents heat soak, keeping incoming air cooler. You will not find a more researched & developed short ram intake for your STI than the Cobb SF. The COBB Tuning SF Intake system is designed around Cobb Accessport maps for maximum efficiency and power. The Cobb Tuning SF Air Box was designed to capture the cool air supplied to the SF intake through the factory intake snorkle. The aluminum 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. All necessary hardware and full illustrated instructions are included.
Intake pending CARB approval
The Cobb Air Box is designed for use with the Cobb SF Intake ONLY.
Its a great product alone but would recommend getting the Airbox with it to help protect it from the heat of the engine
