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.
Add 15-30 WHP to your car! Actual horsepower values will vary depending on other installed hardware, tunes, and the overall condition of your vehicle.
This part is designed and tested to work safely on your stock vehicle (aftermarket catback and intercooler are also ok) without any ECU recalibrating required. If any other parts are installed beyond these listed, or you are using any Cobb AccesssPORT Off-The-Shelf (OTS) tunes, a custom ECU calibration specifically for our intake is REQUIRED. Contact Tech@PERRIN.com for more info.
California and several other states have adopted an emission standard for the regulation of road vehicles created by the California Air Resource Board (CARB). This standard must be met and approved for a system to become CARB certified. When a system becomes approved by meeting the criteria laid out by CARB, it receives a unique identifier known as an EO number and is certified for legal road use.
EO Number: D-735
*Only CARB Approved for 2008-2014 WRX & 2008-2015 STI.
Our intakes are constructed from aluminum tubing, which is precision CNC mandrel bent, for consistent and perfectly 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.
Dryflow filters provide the same level of protection as an oiled filter, but require less maintenance, are less of a mess, and have no risk of over-oiling. The rigid screen inside and around the filter media helps in preventing damage from debris and are ideal for dusty and rough driving conditions.

The airflow straightener improves MAF readings by forcing incoming airflow into a uniform profile. Smooth and predictable airflow is the key to good, consistent MAF sensor readings for reliable horsepower gains.
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 blowoff valve will be much more prominent, demanding attention and alerting people that your car is undeniably modified.
Powder coated for protection against the elements, the textured finish will look awesome for years to come. The PERRIN WRX/STI Cold Air Intake is available in black, red, neon yellow, or pink powder coat.

Warranty & Instructions
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 tech@PERRIN.com
