TiAL Sport QR BOV 2 PSI Spring - Silver (34mm)

If you're tuning a turbocharged vehicle and need to fine-tune your boost control, this 2 PSI spring for the TiAL Sport QR Blow-Off Valve is what you're looking for. This spring is designed to work with the 34mm QR BOV and allows you to adjust the pressure at which the valve opens to vent excess boost. A lower spring pressure means the valve will open sooner, releasing boost at a lower PSI, which can be useful for managing boost creep or achieving a specific boost target.

This particular spring is silver and rated for 2 PSI. It's a well-built component from TiAL Sport, a popular name in the turbocharging world. Swapping out the spring is a straightforward way to alter your BOV's behavior without needing to replace the entire unit. Make sure you have the correct 34mm QR model; this spring is specifically made for that version.
