BOOMBA STI RECIRCULATING VALVE (NATURAL ONLY)

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 over 70psi, allowing it to compliment 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.
