Overview

The PERRIN recirculating blow off valve is a direct upgrade over the OEM unit for boosted Subarus. If you've increased boost, horsepower, or overall performance, the PERRIN BOV responds faster than stock to relieve excess pressure and protect your turbo. Fully adjustable for both release pressure and relief volume — independently — so you can dial it in precisely for your setup.

Features

• Recirculating design — vents back into the intake for closed-loop compatibility
• CNC-machined 6061 billet aluminum cap, piston, and flange
• Body machined from a single block of aluminum — no bolt-on pieces, no potential leak points
• Adjustable release pressure via spring cap — set loose for light loads, tighten for higher boost
• Adjustable relief volume — independent of pressure adjustment
• No special tools required for disassembly or maintenance
