Product Description

Perrin PSP-INT-221 Short Ram Big MAF Intake System Subaru

Perrin PSP-INT-221 Short Ram Big MAF Intake System Subaru

Increase horsepower and style under your hood.The PERRIN Performance BigMAF intake system uses an enlarged MAF housing to allow tuners to use the factory MAF sensor for tuning Subarus with large turbos.

ECU Tuning - The BigMAF intake system requires ECU re-calibration in order to run properly on your vehicle. This BigMaf is designed to do two things:

1 Allow your ECU to accurately measure airflow above and beyond what the stock intake can measure.
2 It is sized specifically to offset the use of 800cc fuel injectors.

Precision Construction - Our intakes are constructed from aluminum tubing which is precision CNC mandrel bent for consistent and perfect fitting parts. Our 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.

T-Bolt Clamps - PERRIN short ram intake systems use high tech T-bolt clamps. Our high end clamps offer maximum holding power and have a built in liner so they will not damage silicone couplers. Each clamp is laser etched with the PERRIN logo.

Color Choice - PERRIN intake systems are powder coated with a wrinkle finish to match your STI intake manifold and/or our PERRIN Front Mount Intercooler tubes. Each system is available in either red, black and silver.

Filter Tech - 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.

5 YEAR Warranty - PERRIN Performance warrants to the original purchaser, all PERRIN products to be free from defects in material and workmanship within a sixty (60) months period from the date of purchase.
