PERRIN Diverter Valve, Red (2022-2023 Subaru WRX)

Enhanced Drivability
Unlike the OEM part, which functions as a simple on/off switch for releasing boost pressure, the PERRIN Diverter Valve offers a smoother boost release. This results in improved drivability and allows for the retention of more boost in specific throttle positions.

No Leak Design
Unlike the OEM part, the PERRIN Diverter Valve will not leak or stick and has no seals that could wear out over time. The diverter valve is 100% recirculating to maintain proper airflow readings in all driving conditions.

No Adjustment Needed
Every PERRIN Diverter Valve comes with two spring options to fit your desired driving style as well as all the essential components to make this a direct bolt-on for your 2022+ WRX. Each valve is designed to work seamlessly right out of the box, requiring no adjustments.

No Tuning Required
Increase horsepower and torque without ECU recalibration or tune! This part is designed and tested to work safely on your vehicle without any tuning required! However, more power can be gained with proper ECU tuning! Confirm any tune or recalibration you add is specific for ALL modifications added to the vehicle.

Finish
The PERRIN Diverter Valve body features a red anodized finish for lasting good looks.
