The TiALSport Q blow-off valve with a 6 psi spring in purple is a BOV for forced-induction engines that provides moderate spring preload for balanced valve response across common boost ranges. The Q-style assembly offers predictable behavior at this intermediate rate. The purple finish offers a more noticeable visual option while preserving the same tuning intent.
