Boomba Racing BPV (2015+ Subaru WRX)

See the video below to observe how badly the stock BPV leaks! We were able to pick up 15 hp and 9 tq from switching to our piece.

This high-performance recirculating bypass valve is precision machined out of aircraft grade billet aluminum. It features an internal brass piston design and is pressure tested to withstand up to 75psi, allowing it to complement even the most aggressive turbo builds. Spring pre-load determines the pressure differential required across the piston before the BOV opens and releases the pressurized intake charge. Designed to be a replacement for the OEM bypass valve, it is available in 4 different colors.

By applying equal amounts of air pressure to both the charge pipe side as well as the vacuum line side of a BPV, we're able to simulate real-world boost conditions. Doing this allows us to test the overall construction of the BPV, including the ability to check for leaks.

Key Features:

• Larger cross-section compared to stock
• 100% recirculating
• Higher flow
• Pressure tested to 75 PSI
• Easy installation
• No need for re-tune

Installation is simple, and all mounting hardware is included.
