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 safe air-fuel ratios and preventing knock and check engine lights that plague competitors.

Precision Construction & MAF Alignment

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.

Optional Heatshield

Keep the hot engine bay air away from your cold air intake with the PERRIN Heatshield for 2022-2023 WRX.

Filter Tech

PERRIN Intake filter elements use open-cell foam to capture dust and dirt. Washable and reusable, PERRIN Foam Filter elements extend the life of your vehicle. Foam filter elements offer superior performance, minimal airflow restriction, and amazing dust-holding capacity.

Finish

Powder coated for protection against the elements, the finish will look awesome for years to come. The PERRIN Cold Air Intake is available in black, red, neon yellow, or pink powder coating.

Sound

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 more prominent.
