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.
Increase horsepower and torque without ECU recalibration or tune! This part is designed to work safely on your vehicle without any tuning required! With our rigorous testing, you can be assured of proper operation and power gains! However, more power can be gained with proper ECU tuning!
Be sure to confirm any tune or recalibration you add is specific for ALL modifications that have been added to the vehicle. If you have any questions, please contact us!
*The PERRIN Cold Air Intake for 2008-2014 WRX & 2008-2015 STI are only CARB Approved up to 2015 STI.
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!
