2015-2021 Subaru WRX Perrin Cold Air Intake ( Black or Red )

The Perrin Cold Air Intake for the 2015-2021 Subaru WRX is engineered to increase horsepower and torque while effectively reducing turbo lag. This system features a CNC mandrel-bent aluminum tube finished in a durable black textured powder coating. It includes a high-flow Dryflow filter that requires no oil, ensuring consistent airflow and filtration. The included heat shield redirects hot engine air away from the intake, maintaining near-ambient intake temperatures. PERRIN utilizes precise MAF sensor alignment and specific plumbing dimensions to maintain correct air-fuel ratios and prevent check engine lights. This intake provides a subtle sound during normal driving and a more prominent blowoff valve note under load. For peak performance and safety, we strongly recommend pairing this upgrade with a [custom etune from Migtuned](https://migtuned.com), specifically calibrated for your vehicle's year and model.
