Cobb's SF WRX/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 WRX 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 WRX than the Cobb SF. The COBB Tuning SF
Intake system is designed around Cobb Accessport maps for maximum efficiency
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.
