Product Details

What you get here is the TiAL Sport QR BOV 11 PSI Spring in black, designed for their 1.5-inch blow-off valves. This spring is what sets the opening pressure for your blow-off valve, and this specific one is calibrated to release boost pressure at 11 PSI. It’s a straightforward component that directly impacts how your turbo system behaves under boost.

TiAL Sport is known for making well-built components for performance applications, and this spring is no different. It’s made to be a direct replacement for the spring that came with your TiAL Sport QR blow-off valve. Swapping out the spring is a common way to adjust when your blow-off valve opens, allowing you to tune it to your specific turbo setup and boost levels. If your current spring is worn out or you need to change your boost threshold, this is the part you’ll need.

Remember, this part is not CARB approved and cannot be shipped to California. Make sure your turbo system is set up to handle the boost levels this spring is designed for.
