The TiALSport Q blow-off valve with an 8 psi spring in silver is a BOV for forced-induction engines that provides a firmer spring preload for higher threshold boost relief. The Q-style configuration delivers consistent response at this setting. The silver finish keeps a clean look while offering a higher-rate spring option for tuning toward stronger boost levels.
