Product Description

The TiALSport 004939 QR Recirculating Blow-Off Valve is a universal performance component for turbocharged engines needing efficient boost venting and smooth recirculation into the intake tract. Built with a 34 mm valve and a 10 PSI spring, this valve provides improved throttle response and reliable boost control for a range of street and track applications. Its black anodized finish and precision CNC construction deliver durability and resistance to heat and corrosion in demanding operating conditions.

Designed with a recirculation port, V-band mounting clamp, and included weld flange, the QR valve integrates cleanly with existing turbo systems where factory-like recirculation is preferred. A banjo-style air fitting with an oversize hose barb enhances actuator response, while the reinforced diaphragm and quality machining provide long life and dependable operation. Because this is a universal component, verify flange and piping compatibility before installation for best performance.
