Process West 72mm Cold Air Intake - Subaru WRX / STI (GE/GH/GR/GV)
The Process West 72mm Cold Air Intake is a direct replacement for the factory air box and intake on the 2008–14 Subaru WRX and STI. It cuts restriction in the intake path for better airflow into the engine, and a K&N high-flow filter is included. The factory airflow meter bolts straight into a machined mount, so no modification is needed. Expect a stronger induction note under acceleration.
Note: Installation by a professional is recommended.
Features
- 72mm CNC mandrel-bent aluminium tube in a black finish
- Machined airflow meter mount retains the factory airflow meter without modification
- K&N high-flow air filter included
- Direct replacement for the factory intake with no cutting or permanent changes
