Frequently Asked Questions
PERRIN Recirculating Blow Off Valve
The PERRIN Recirculating Blow Off Valve (BOV) is designed to provide faster and more reliable boost pressure relief for modified Subaru WRX and STI models. If you’ve increased your vehicle’s boost, horsepower, or overall performance, this upgraded BOV responds quicker and more precisely than the OEM unit, protecting your turbo and improving throttle response.
Crafted from CNC-machined 6061 billet aluminum, the BOV body is machined from a single block, eliminating leak-prone bolt-on pieces. The cap, piston, and flange are also billet aluminum for maximum durability and precision.
An adjustable spring cap lets you fine-tune the release pressure independently of the blow-off volume. Loosening the cap provides a smoother, lighter boost release for mild setups, while tightening it suits higher boost pressures. Adjusting the volume controls how much air is vented, allowing you to prevent turbo damage from insufficient venting or poor throttle response from excessive venting.
Maintenance is simple—disassembly requires no special tools and the valve is easy to service when needed.
