Where to Buy
Visit manufacturer pageThe Perrin Diverter Valve is a functional turbo-system upgrade aimed at improving drivability and reducing boost leaks with a fully recirculating design. Perrin emphasizes that it is boost-leak free, designed for 2022+ WRX fitment, and does not require tuning, which makes it a strong supporting part for owners wanting more consistent response and a more robust alternative to the factory valve behavior.
