Upgrade your intake system with the Process West 72mm Cold Air Intake, designed as a direct replacement for the factory setup on 2008–2014 Subaru WRX and STI (GRB chassis). Engineered to reduce intake restriction, this system improves airflow into the EJ engine for better performance and throttle response.


Improved Intake Sound

By eliminating the restrictive factory airbox, this intake produces a noticeable increase in induction sound, delivering a deeper and more aggressive tone under acceleration without requiring additional modifications.


Precision Engineered Construction

Constructed from lightweight CNC mandrel-bent aluminum tubing, the 72mm intake provides a smooth, consistent airflow path. A machined airflow meter mount allows you to retain the factory MAF sensor without modification, ensuring proper operation and easy installation. The system is finished in a durable black coating for a clean, OEM-style appearance.


High-Flow Filtration Included

Each kit includes a high-flow K&N air filter, designed to increase airflow while maintaining excellent filtration. The reusable design makes long-term maintenance simple and cost-effective.


Straightforward Installation

This intake is a true bolt-on upgrade, requiring no cutting or permanent modifications—making installation quick and hassle-free.
