Increase horsepower and style under your hood. The PERRIN Cold Air Intake (CAI) system uses proper MAF alignment and tubing size, which are crucial for maintaining proper air-fuel ratios and preventing check engine lights that plague competitors.
PERRIN Intake systems use proper MAF alignment and plumbing size, both of which are crucial to maintaining proper air-fuel ratios and preventing check engine lights that plague competitors. Eliminating intake restrictions and increasing flow potential allows for faster turbo spooling, reduces turbo lag, and broadens the power band.
The PERRIN Cold Air Intake for 2015-2021 WRX comes with a heat shield to redirect hot engine air away from the intake to allow for near ambient air intake temperatures.
The OEM MAF sensor wiring harness is too short to work with the PERRIN Cold Air Intake. Provided with each kit is a MAF sensor extension. This extension comes with OEM plug ends to relocate the MAF sensor with no compatibility issues.
During normal driving, the PERRIN intake sounds relatively stock. However, under load it really comes to life, unlocking the sound of your turbo flat-4. Once installed, the sound of your blow off valve will be much more prominent, demanding attention and alerting people that your car is undeniably modified.
NOTE: This intake system requires no tuning to operate properly and safely! However, if you choose to add an upgraded downpipe or tune, you must choose a tune that is specific to either the PERRIN or AEM Intake System. MAF curves for any other intake (including the OEM Air Box) will not work properly and you will damage your engine! Always contact a qualified tuner prior to adding any ECU mapping to your vehicle! If your tuner requests a MAF Curve, we do have those available upon request. Questions?: Please contact us!
