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

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.

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.

Constructed from precision CNC mandrel bent aluminum tubing for consistent and perfect fitting parts. Their 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.
