TiAL 002970 QR Recirculating Blow Off Valve Compact BOV

The TiAL 002970 QR is TiAL Sport's compact recirculating blow off valve (BOV), engineered for performance turbocharged applications where space is at a premium. The QR delivers the same proven TiAL quality and response as the full-size Q series, packaged in a more compact form factor ideal for tight engine bays.

The QR uses the standard TiAL V-band flange for easy, leak-free installation and a secure seal under high boost conditions. It ships configured as a recirculating BOV and can be converted to an atmospheric (vented to atmosphere) BOV by swapping to the standard Q BOV cap — giving you flexibility for different builds and tuning preferences.

Recirculation Port Options:

• 1.0" port — Compatible with Subaru applications
• 1.29" port — Compatible with Nissan GT-R (GTR) applications
• 1.34" port — Compatible with DSM and Mitsubishi Evo applications
