What does this 8 PSI spring do?

This spring is installed inside the TiAL Sport QR blow-off valve. It determines the boost pressure threshold, meaning the valve will open to release excess boost when your turbocharger reaches approximately 8 PSI.

Can I use this spring with any blow-off valve?

No, this spring is specifically designed for the TiAL Sport QR model blow-off valve. Using it with other valve types may not provide correct function or fit.

What other parts do I need to use this spring?

You will need the TiAL Sport QR blow-off valve body itself to install this spring. It's a replacement part for the spring that comes standard with the valve.
