What does changing the spring in my TiAL QR BOV do?

Changing the spring alters the boost pressure required for the blow-off valve to open. A stiffer spring, like this 11 PSI version, means more boost pressure is needed before the valve will vent excess turbo pressure.

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

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

What is the difference between the spring colors?

The different spring colors offered by TiAL Sport correspond to different boost pressure ratings. The purple spring is intended for applications running approximately 11 PSI of boost.

Product Details

This is the TiAL Sport QR BOV 11 PSI Spring, designed for their 34mm blow-off valves. The purple spring is rated for 11 PSI of boost pressure. It's a direct replacement for the spring that came with your TiAL QR BOV, allowing you to fine-tune your boost control. If you're looking to adjust the boost threshold your blow-off valve opens at, this spring is what you need.

TiAL Sport is known for well-built turbo components, and this spring is no different. It's made to precise specifications to ensure consistent performance. The spring's tension dictates the amount of boost pressure required to open the valve, so changing it directly affects when your blow-off valve will vent excess boost. This purple spring is a popular choice for applications running around 11 PSI of boost.

Remember, this part is not CARB approved and cannot be shipped to California. Always refer to your vehicle's specific tuning requirements and the manufacturer's instructions when making adjustments to your boost control system.
