Add to Wishlist


Perrin's Afta-Maf silicone airbox hose for the 2002-2007 WRX & 2004-2007 STi features 5-ply silicone construction and vibrant color. Replacing the stock corrugated rubber hose between the turbo inlet and factory airbox will allow for improved airflow due to higher internal volume and smoother airflow due to the smooth interior. This product is the perfect compliment to a Perrin turbo inlet hose. The Perrin WRX & STi MAF hose is designed for use with the stock airbox, but will work with any intake designed to use the stock rubber hose.
