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

The spring inside a blow-off valve keeps it sealed against boost pressure when your throttle is closed. It needs to be strong enough to hold boost but flexible enough to vent excess pressure when the throttle is suddenly released.

How do I know if I need a different spring for my TiAL Sport QR BOV?

If your vehicle is tuned for a specific boost level, you'll want a spring that matches that pressure. If your current spring is leaking boost or not venting effectively, a different rate spring might be necessary.

Can I use this spring with other brands of blow-off valves?

No, this spring is specifically designed for the TiAL Sport QR (Quick Release) blow-off valve. Using it in a different brand or model of BOV may result in improper fitment and function.

Product Details

If you're tuning your turbocharged vehicle and need to precisely set your blow-off valve's opening pressure, this 12 PSI spring from TiAL Sport is what you're looking for. This red spring is specifically designed for the TiAL Sport QR (Quick Release) blow-off valve and is rated to open at 12 pounds per square inch of boost. Getting the right spring rate is crucial for proper boost management; too soft and it might leak boost, too stiff and it won't vent excess pressure effectively, potentially causing compressor surge.

This well-built spring is made from durable materials to withstand the heat and pressure cycles found in forced induction systems. It's a direct replacement for the spring that comes standard with many TiAL Sport QR BOV kits, allowing you to fine-tune your setup without replacing the entire valve. The 29mm size ensures it fits correctly within the valve body, maintaining a solid seal when closed and a clean release when needed.

Remember, this spring is not CARB approved and cannot be shipped to California. Always refer to your vehicle's specific tuning requirements and the TiAL Sport installation guide to ensure you select the correct spring for your boost levels.
