PERRIN Cold Air Intake — 15–21 WRX (Red)

More horsepower, better sound, and a cleaner engine bay. The PERRIN Cold Air Intake uses proper MAF alignment and correct plumbing sizing to maintain accurate air-fuel ratios and prevent the check engine lights that plague competitor intakes. CNC mandrel-bent aluminum tubing ensures consistent, perfect-fitting parts every time.

Key Features

• CNC mandrel-bent aluminum tubing for consistent fitment and airflow
• CNC-machined MAF sensor bung for perfect alignment — critical for proper AFR and ECU management
• Included heat shield redirects hot engine air away from the intake for near-ambient intake temps
