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:
Allow your ECU to accurately measure airflow above and beyond what the stock intake can measure.
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.
Sound
With a PERRIN intake system your car will make a throaty, deep tone on throttle that is undeniably modified. You will be able to hear your turbo spooling and hear your blow off valve every time it opens. Even the stock one.
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 Choices
This PERRIN Performance product features a durable powder coat finish. PERRIN powder coating is available in either red or black and is accented with a wrinkled texture finish.
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.
