Precision Turbo PTE PB64 Race Blow Off Valve 64 mm

High quality premium 64 mm open BOV with aluminum weld-on flange

Precision Turbo open blow off valve comes with aluminum flange and connection fittings

Made of lightweight 6061 and 7075 aluminum, PTE's 64mm BOV is anodized  matte black to be aesthetically pleasing yet functional and provide  long-lasting protection from the elements. It features a Kevlar  reinforced silicone diaphragm for quick response and a hard anodized  valve stem for improved durability. The PB64 also features a CFD  designed valve and valve body for highest flow even at low lift, while  the attached O-ring seal prevents leaks. In addition, PTE's PB64 BOV  features an innovative and industry-unique wave spring that provides  additional weight savings and keeps the valve closed at idle, even at  high vacuum.

PTE's PB64 BOV is designed to release the back pressure created when the  throttle valve closes via a spring-loaded valve-diaphragm assembly. It  is a key component in preventing potentially damaging volume blowback  back into the compressor to reduce wear on both the turbo and the  engine. The PB64 comes with an aluminum weld-on flange, spring  adjustment screw and two top ports.
