TiAL Sport QR BOV 12 PSI Spring - Purple (1.0in)

If you're tuning a turbocharged vehicle and need to fine-tune your boost pressure, this 12 PSI spring for the TiAL Sport QR blow-off valve is what you're looking for. This purple-colored spring is designed to work with the TiAL Sport QR BOV, allowing you to set a specific boost threshold. It's a well-built component that helps ensure your blow-off valve opens at the intended pressure, protecting your turbocharger from overboost conditions.

This spring is a direct replacement for the spring that comes standard with the TiAL Sport QR BOV. Swapping it out is a straightforward process that can be done with basic tools, typically without removing the BOV from the vehicle. By changing the spring, you're essentially changing the pressure at which the BOV's diaphragm is held closed. A stiffer spring, like this 12 PSI version, requires more boost pressure to overcome its force and open, thus allowing you to run higher boost levels safely. This is a solid option for those looking to increase boost pressure beyond the stock spring's capability.
