The TiALSport Q blow-off valve with a 10 psi spring in black is a BOV for forced-induction engines that provides controlled boost relief through a defined spring preload. The Q-style design gives tuners a predictable valve response at that spring rate. This black finish variant offers the same tuning-focused function while matching common engine-bay aesthetics.
