Perrin BIG MAF Intake Kit – Subaru WRX STi

The Perrin BIG MAF intake is officially discontinued. If you need a high quality intake for your Subaru we highly recommend using the Cobb SF intake or Cobb redline Carbon Fiber intakes. If you are worried about maxing out the MAF sensor we also offer Etune services for SD and SD hybrid maps that will get your car running right without the need for a BIG maf housing.

The Perrin BIG MAF intake has been proven to perform time and time again. Perfect applications with larger injectors, turbo and ECU tuning. 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.

Choice of color

Perrin 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.
