What does changing the blow-off valve spring do?

Changing the spring alters the pressure at which the blow-off valve opens. A stiffer spring, like this 6 PSI purple one, requires more boost pressure to open, which can help prevent boost leaks on higher-powered setups. A weaker spring opens sooner.

How do I install this spring?

Installation typically involves disassembling the blow-off valve body, removing the old spring, and inserting the new one. It's a relatively simple process for those familiar with turbo components. Refer to the manufacturer's instructions for specific details.

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

This spring is specifically designed for TiAL Sport 34mm QR Blow-Off Valves. Using it with other brands or different sizes of blow-off valves is not recommended and may not fit or function correctly.
