What does a blow-off valve spring do?

The spring inside a blow-off valve (BOV) holds the valve closed against intake manifold vacuum and helps it open at a specific boost pressure. A stiffer spring, like this 10 PSI version, requires more boost pressure to open the valve.

Will this spring fit any blow-off valve?

No, this spring is specifically designed for the 29mm TiAL Sport QR Blow-Off Valve. Using it in a different model or size BOV may result in improper fitment or function.

Can this part be shipped to California?

No, this part is not CARB approved and cannot be shipped to California due to emissions regulations.
