Subaru WRX 2015-2021

The Process West Cold Air Intake is a direct replacement intake system designed for the 2015–2021 Subaru WRX (VA chassis, FA-series engine). Engineered to reduce intake restriction and improve airflow, this upgrade enhances throttle response, induction sound, and overall engine efficiency without requiring permanent modifications.

Improved Intake Sound & Driving Experience

Replacing the factory airbox allows the FA-series engine to breathe more freely, producing a noticeably deeper and more aggressive induction sound under acceleration. The improved airflow path enhances the driving experience while maintaining daily drivability.
