TiAL 002972 QR Recirculating Blow Off Valve

The TiAL QR Blow Off Valve is TiAL's compact recirculating BOV designed for performance forced induction applications. Built to the same exacting standards as TiAL's legendary Q series, the QR delivers precise, reliable pressure relief in a smaller, more packaging-friendly form factor — making it ideal for tight engine bays where space is at a premium.

The QR ships ready for recirculating (recirc) duty and features an optional recirculation port to suit several popular platforms, available in three sizes: 1.0" (Subaru), 1.29" (Nissan GT-R), and 1.34" (DSM/Mitsubishi Evo). It uses TiAL's industry-standard V-band flange connection for a secure, leak-free seal that is easy to install and remove.

Key Features:

• Compact recirculating blow off valve design — ideal for space-constrained engine bays
• Optional recirculation port in three sizes: 1.0" (Subaru), 1.29" (GT-R), and 1.34" (DSM/Evo)

The TiAL QR is a versatile, high-performance blow off valve solution that offers the flexibility to run either recirculating or atmospheric configurations, making it a popular choice among turbocharged enthusiasts and professional builders alike.
