Cobb 08-14 Subaru WRX/STI Airbox
The SF Air Box adds the benefits of a cold air intake to the outstanding performance of the SF Intake. The factory inlet directs cold air from the front grill to the SF Airbox, which encloses the SF Intake. Hot engine bay air that robs horsepower is prevented from entering the intake system to provide consistent intake performance. This unique design also separates rainwater from the intake air, eliminating the water ingestion issues that plague in-fender cold air intakes. This intake airbox is constructed of 16 gauge aluminum, consisting of a one-piece surround, directional lid, stainless steel hardware, and all the necessary components for a seamless install with OEM quality fit and finish.
