TiAL 004043 QR Blow Off Valve Recirculating Compact BOV

The TiAL QR Blow Off Valve (BOV) is TiAL's compact recirculating bypass valve, engineered for forced induction applications where space is at a premium without sacrificing performance or reliability. Built to the same exacting standards as TiAL's flagship Q BOV, the QR features a smaller overall footprint while retaining the proven internal design that enthusiasts trust.

Key Features:

• Compact recirculating design — ideal for tight engine bays where space is limited
• Multiple recirculation port options — fits a variety of popular platforms with optional port sizes: 1.0" (Subaru), 1.29" (Nissan GT-R), and 1.34" (DSM/Mitsubishi EVO)
• Standard TiAL V-Band flange — ensures a secure, leak-free connection and easy installation
• Convertible to atmospheric venting — can be converted into a standard TiAL Q BOV by swapping the recirculation cap for open-air venting
• Precision-machined construction — manufactured from high-quality aluminum for durability and long service life
• Piston-style valve — provides fast, consistent response under varying boost pressures

The TiAL QR is an excellent choice for street and track builds where a recirculating valve is required or preferred, such as vehicles running MAP sensors that are sensitive to metered air being vented to atmosphere. Its versatility across multiple popular platforms and its compatibility with TiAL's standard V-Band mounting system make it a straightforward upgrade or replacement BOV.
