The TiAL Sport QR blow-off valve is a 34mm unit fitted with an 11 PSI spring and finished in black, providing a notably firm opening threshold for controlled compressor pressure release in forced-induction systems. The stiffer spring rate and compact design suit higher-boost setups, ensuring predictable venting characteristics with a low-profile black appearance.
