The Perrin CAI for the 2015+ Subaru WRX is the perfect mod for anyone looking to gain some power and increase the engine sound tone. BOV sound will be more prominent with this setup during WOT.
This is a bolt-on setup that will NOT require tuning, as it was designed by Perrin to provide the proper air-fuel ratio without any CEL.
All colors come with matching color heat shield.
