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

The spring inside a blow-off valve maintains a seal against boost pressure until a set point is reached. This 12 PSI spring ensures the valve opens only when your system's boost pressure exceeds 12 PSI, protecting your turbocharger.

Can I use this spring in a different brand of blow-off valve?

This spring is specifically designed for the TiAL Sport QR blow-off valve model. Using it in a different brand or model of blow-off valve is not recommended, as it may not fit correctly or function as intended.

Product Details

This 12 PSI spring is specifically made for the TiAL Sport QR blow-off valve, featuring a 29mm diameter and a silver finish. It's a direct replacement part designed to maintain the correct boost pressure threshold for your turbocharged vehicle. When you're looking to fine-tune your boost control or replace a worn-out spring, this component ensures your blow-off valve operates as intended, releasing excess pressure effectively to protect your turbocharger.

The spring's tension is calibrated to open at approximately 12 PSI, which is a common setting for many performance applications. Using the correct spring is crucial for proper blow-off valve function; too weak and it might leak boost, too strong and it won't open when needed. This well-built spring from TiAL Sport is designed for reliable performance, helping to prevent compressor surge and maintain consistent boost levels. It's a straightforward swap for the existing spring in your TiAL QR BOV, requiring no special tools beyond what's needed to disassemble the valve itself.
