TiALSport Q Blow-Off Valve - 10 PSI Spring - Black

The TiALSport Q is a 50mm vent-to-atmosphere blow-off valve for turbocharged and supercharged engines, CNC machined from 6061 aluminum alloy with a black anodized body. It ships with the 10 PSI spring, which sets the valve opening pressure, and includes the Q valve assembly, V-band clamp, V-band weld flange, air fitting, and high-pressure O-ring. The Q design flows significantly more air than the original BV50 and supports high-horsepower single-valve setups.
