The TiALSport Q blow-off valve with a 2 psi spring in silver is a BOV for forced-induction engines tuned for very light preload, offering early valve lift for low boost thresholds. The Q-style design produces a predictable response at this low spring rate, useful when a gentler release is needed. The silver finish provides a neutral, unobtrusive look.
