Product Description

The PERRIN PSP-INT-327RD Cold Air Intake is a purpose-built performance upgrade for the 2022-2025 Subaru WRX with the 2.4 L turbocharged boxer engine. Designed to preserve MAF alignment and eliminate airflow restrictions, it delivers dyno-proven gains of 10-20 wheel horsepower and 10-17 lb·ft torque--all with no ECU tuning required.

Constructed of mandrel-bent aluminum with a clean red powder coat and paired with a washable foam filter, this system improves turbo response and provides a more aggressive induction note during full throttle. Installation is straightforward using OEM mounts, and while a heat shield is optional, the included hardware ensures a seamless fit. Backed by a 5-year warranty, the PSP-INT-327RD is a solid package--though it's not CARB compliant, making it unsuitable for use in California and similar jurisdictions.
