The TiAL Sport Q BOV 12 PSI spring in blue is a replacement spring calibrated to open the Q-series blow-off valve at 12 PSI. It provides a defined mechanical opening threshold so technicians can adjust the valve's venting point by swapping springs rather than modifying the valve body, simplifying tuning of blow-off behavior.
