🖤 Blow off the competition with the highest flowing BOV on the market!
The TiAL Q.11BK Q Series Blow Off Valve features a black anodized aluminum flange and an 11 PSI spring, delivering 60% more airflow than the original TiAL BOV. Designed for universal fitment on standard TiAL flanges, it offers a plug-and-play upgrade that enhances turbo efficiency and sound without requiring modifications.

Lubricate sealing seal on piston before installing
At first I had problems since the spring probably has been sitting in the valve while its sitting in stock or the warehouse so it wouldn't open. I used a vacuum pump to add about 26 psi than lubed the o ring which was stuck. Once you lubricate it and add a 1/4 vaccum line since any small will cause a delay response valve works great.
