The PERRIN Diverter Valve for 2022+ WRX releases boost pressure more naturally for improved drivability. It features a durable, 100% recirculating, boost leak-free design with no seals to wear out and a long-lasting red anodized finish.

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
