Boomba Racing Blowoff Valve Ford Focus ST 2013+

This high performance VTA (vent to atmosphere) blow-off 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 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. Designed to be a replacement for the OEM and available in 4 different colors, this blow-off valve is sure to compliment any ST engine bay.

Installation is simple and all mounting hardware are included.
