PERRIN 02-07 Subaru WRX/STi Cold-Air Intake - Black

The PERRIN Cold Air Intake system increases horsepower and adds style under the hood. It features proper MAF alignment and plumbing size to maintain correct air/fuel ratios and prevent check engine lights. The intakes are constructed from precision CNC mandrel-bent aluminum tubing. The MAF sensor bung is CNC machined for perfect fit and alignment. The filter elements use open-cell foam, which is washable, reusable, and offers superior performance with minimal airflow restriction and excellent dust-holding capacity. This intake system will produce a throaty, deep tone and allow you to hear the turbo spooling and blow-off valve.
