Precision Turbo dives farther into the Blow Off Valve (BOV) scene with the highly anticipated PB50 Blow Off Valve. This BOV features a massive 50mm valve for venting off air as quickly as possible, perfect for your medium to high boost racing applications. On the outside this valve is constructed from lightweight 6071 and 7075 billet aluminum with an aesthetically pleasing black anodized finish.

Inside is where this valve truly shines. This vent to atmosphere blow off valve features a low-resistance rolling diaphragm assembly. Keeping this valve closed and air tight at idle is Precision's innovative proprietary wave spring and O-Ring seal. When actuated the hard-coat anodized valve stem and rolling diaphragm provide quick response and unmatched durability.

This valve is generally compatible with most aftermarket manual and electronic boost controllers on the market today. Each unit is also warranted free from manufacturer's defect for a period of 12 months or 12,000 miles.
