Perrin Cold Air Intake System Subaru WRX STI 08-12

Increase horsepower and style under your hood. The PERRIN Performance intake system uses proper MAF alignment and plumbing size, which are crucial to maintain proper air fuel ratios and prevent check engine lights that plague competitors. These intakes are constructed from aluminum tubing which is precision CNC mandrel bent for consistent and perfect fitting parts. The MAF sensor bung is CNC machined for perfect fit and alignment of MAF sensor to intake. This is crucial for proper air fuel ratios and ECU engine management.

All PERRIN intake systems use high tech T-bolt clamps instead of the typical less expensive worm drive clamps. These high end clamps offer maximum holding power and have a built in liner so they will not damage silicone couplers. Finally, each clamp is laser etched with the PERRIN logo. PERRIN Performance intake filter elements use open cell foam to capture dust and dirt. Washable and reusable, PERRIN foam filter elements can last the life of your vehicle. Foam filter elements offer superior performance for turbo charged vehicles with minimal airflow restriction and amazing dust holding capacity. Increasing the longevity of your turbo.

The PERRIN intake system works great as a bolt on intake for a stock car with stock tuned ECU. It is NOT OK to use with a Reflashed/Tuned ECU, unless it is tuned specifically for the PERRIN intake system. Because of the 08+ MAF sensor being very sensitive, any change of the intake system causes the car to run lean. A library of PERRIN Performance custom tuned AccessPORT maps for their intake are provided for free to existing AccessPORT customers.

PERRIN intake systems are powder coated with a wrinkle finish to match your STI intake manifold and/or the PERRIN Front Mount Intercooler tubes. Each system is available in either red, black or silver. Please make your selection below.
