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

This spring sits inside your TiAL QR blow-off valve and provides the necessary tension. It determines the boost pressure threshold at which the valve will open to release excess pressure.

How do I know if I need a 12 PSI spring?

You would typically choose a 12 PSI spring if your vehicle's turbo system is designed to operate at or around that boost level. It's important to match the spring's rating to your engine's boost requirements for proper operation.

Can this spring be used with other brands of blow-off valves?

No, this spring is specifically designed for TiAL Sport's 34mm QR blow-off valves. Using it with other brands or different TiAL models may not provide correct fitment or function.

Product Details

TiAL Sport is well-known for making high-performance turbocharger components, and this 12 PSI spring is a prime example of their focus on boost control. This blue-colored spring is designed specifically for their 34mm QR (Quick Release) blow-off valves. It's what helps your blow-off valve open and close at the right time to manage boost pressure effectively.

When you're running a turbocharged or supercharged engine, managing boost is critical. Too much pressure can be hard on your engine, and too little means you're not getting the performance you paid for. This spring is calibrated to open the blow-off valve when your system reaches 12 PSI. It’s a well-built component that ensures your TiAL QR BOV functions precisely as intended, helping to protect your turbocharger and maintain consistent power delivery. The 34mm size means it's made to fit their specific QR model blow-off valves.

Keep in mind that this part is not CARB approved and cannot be shipped to California. If you're looking to fine-tune your boost pressure with a reliable component from a respected name in forced induction, this spring is a solid option.
