What does the spring in a blow-off valve do?

The spring inside a blow-off valve keeps it closed under normal engine vacuum and low boost conditions. It requires a certain amount of boost pressure to overcome its tension and open, releasing excess pressure.

How do I know if I need a different spring rate?

You might need a different spring if your blow-off valve is leaking boost (spring too weak) or not opening properly under boost (spring too stiff). This 10 PSI spring is ideal if your target boost pressure is around that level.

Does this spring come with any other hardware?

This product is the 10 PSI spring only. It is designed to be a direct replacement for the spring that came with your TiAL Sport QR Blow-Off Valve.

Product Details

This 10 PSI spring for your TiAL Sport QR blow-off valve is made from durable steel and is color-coded blue for easy identification. It's designed to ensure your blow-off valve opens reliably at precisely 10 PSI of boost pressure. This is crucial for protecting your turbocharger from over-pressurization and ensuring consistent performance.

TiAL Sport is known for well-built turbo components, and this spring is no exception. It's a direct replacement for the spring that came with your QR BOV, meaning it fits right in without any modifications. Having the correct spring rate is key to proper blow-off valve function; too weak and it might leak boost, too strong and it won't open when it should, potentially damaging your turbo. This 10 PSI spring is a popular choice for many turbocharged applications where that specific boost threshold is desired.

When installing, make sure your blow-off valve is clean and free of debris before swapping the spring. This ensures the valve can move freely and seal properly. If you're looking to adjust your boost threshold or replace an old spring, this blue 10 PSI option is a solid choice.
