370z Tial Sport Q BOV Blow Off Valve

Tial Sport's new Q Blow Off Valve is a newer version of the original 50mm BOV. Featuring an improved design through countless hours of R&D, Tial was able to increase 60% more flow than the original design. This is now believed to be the highest flowing on the market. Made from 6061 aluminum alloy with a 50.5mm valve and V-band clamp mounting, this new version just got better.
