This is the Boomba Racing Blow Off Valve. This is a high-performance recirculating blow off valve that has been fabricated from machined aircraft grade billet aluminum that features an internal brass piston that has been pressure tested to withstand up to 75psi of pressure. This means it is strong enough to handle the most aggressive of turbo builds. The spring pre-load will determine the pressure differential required across the piston before the BOV opens and releases the pressurized intake charge.
This is a direct replacement of your OEM bypass valve and will come provided with a vacuum line. Additionally, this particular blow off valve will come in an anodized black finish for extra protection against corrosion, and to add a cleaner look to your engine bay.
