What is the purpose of a blow-off valve spring?

The spring inside a blow-off valve (BOV) keeps the valve sealed against boost pressure. It needs to be strong enough to hold boost but weak enough to open when the throttle is closed suddenly, releasing excess pressure to protect the turbo.

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

If your blow-off valve is leaking boost, not opening when it should, or opening too soon, you might need to change the spring rate. This 6 PSI spring is suitable for setups targeting that specific boost level.

Does this spring come with any other hardware?

This product is for the 6 PSI blue spring only. It is designed to be a direct replacement for the spring within your existing TiAL Sport QR Blow-Off Valve assembly.

Product Details

This blue spring is specifically rated for 6 PSI of boost pressure, making it a direct replacement for your TiAL Sport QR Blow-Off Valve. It's a well-built component designed to help your turbo system vent excess pressure effectively. Using the correct spring rate is crucial for proper BOV operation, ensuring it opens at the intended boost level to protect your turbocharger from over-boosting and potential damage. This particular spring is made from durable materials to withstand the heat and pressure cycles common in forced induction systems.

When you're tuning your turbocharged vehicle, the spring rate in your blow-off valve plays a key role in how the system behaves. A 6 PSI spring is a popular choice for many setups where precise boost control is desired. It's designed to fit the TiAL Sport QR model, ensuring a straightforward installation process if you need to swap out your existing spring or want to adjust your boost threshold. The blue color is a visual indicator of its 6 PSI rating, helping you identify it easily.
