TiAL 004041 QR Blow Off Valve Compact Recirculating BOV

The TiAL QR Blow Off Valve (BOV) is TiAL's compact recirculating blow off valve, engineered for high-performance forced induction applications. Built around the same trusted internals as the legendary TiAL Q BOV, the QR features a more compact form factor specifically designed for engine bays where space is at a premium.

The QR uses TiAL's standard V-band flange for a secure, leak-free connection and can be converted into a standard TiAL Q BOV with a simple swap of the top housing. An optional recirculation port is available in three sizes to accommodate a variety of popular platforms: 1.0" (Subaru), 1.29" (Nissan GT-R), and 1.34" (DSM/Mitsubishi Evo), making it a versatile choice across many builds.

Key Features:

• Compact recirculating blow off valve design
• Uses the standard TiAL V-band flange for easy installation and a secure seal
• Convertible to a standard TiAL Q BOV by swapping the top cap
• Optional recirculation port sizes: 1.0" (Subaru), 1.29" (GT-R), or 1.34" (DSM/Evo)
• High-quality construction consistent with TiAL's motorsport-grade standards
• Ideal for turbocharged applications requiring a low-profile BOV solution

The TiAL QR is a top choice for enthusiasts and professional builders who demand reliable, proven blow off valve performance without sacrificing valuable space in a crowded engine bay.
