CPBB Tuning SF Air Box - 02-07 WRX/STi

The COBB Tuning SF Air Box was designed to capture the cool air supplied to the SF Intake through the factory intake snorkle. 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.

Unlike some cold air intakes, which places the filter in the front fender, our design helps to supply cool air through factory ducting, while eliminating the risk of water ingestion. Comes with all necessary hardware and full illustrated instructions.
