Precision Turbo and Engine - PTE 64mm Blow Off Valve - PBO 083-2010

It features a Kevlar-reinforced silicon rolling diaphragm for quick response and a hard-coat anodized valve stem for enhanced durability. The PB64 also has a CFD designed valve and valve body for the highest flow even at low lift, while the attached O-ring seal prevents leakage.

Furthermore, PTE's PB64 BOV also utilizes an innovative and industry-first proprietary wave spring for added weight savings while still holding the valve closed under high vacuum idling.

Designed to release back up pressure created when the throttle is closed via a spring-loaded valve diaphragm assembly, PTE's PB64 BOV is a key component for preventing potentially harmful compressor surge back into the turbocharger to reduce wear on both the turbo and engine.

Packaged with a weld-on aluminum mounting flange, spring adjustment screw, and two top ports for the ulitmate in versatility and adjustability, the high-performance PB64 is generally compatible with most aftermarket manual and electronic boost controllers on the market today.
