Perrin Diverter Valve (Red), 2022-2025 WRX

The primary role of a diverter valve is to maintain drivability and eliminate boost leaks. Many factory diverter valves have plastic seals and suboptimal designs that allow boost pressure to escape, reducing power and forcing the turbo to work harder.
The PERRIN Diverter Valve provides a smoother boost release compared to the OEM part, which operates as a basic on/off switch for releasing boost pressure. This design enhances drivability and helps retain more boost in specific throttle positions, optimizing performance.
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.
The PERRIN Diverter Valve for the 2022+ Subaru WRX includes two spring options to match different driving styles, ensuring optimal performance. It is designed for a hassle-free installation and has all the necessary components for a direct bolt-on fit. Engineered to work seamlessly out of the box, this upgrade requires no adjustments.
The PERRIN Diverter Valve body features a red anodized finish for lasting good looks.
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!
