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

Changing the spring alters the boost pressure required to open the blow-off valve. A lower pressure spring, like this 2 PSI version, will allow the valve to open sooner, helping to vent excess boost more quickly and potentially reduce turbo lag.

Is this spring compatible with all TiAL Sport blow-off valves?

No, this specific 2 PSI spring is designed only for TiAL Sport's 29mm QR (Quick Release) blow-off valve models. It is not compatible with other sizes or models of TiAL Sport BOVs.

Does this spring come with any hardware or instructions?

This product is just the replacement spring itself. It does not include additional hardware or installation instructions. You will typically reuse the existing components from your TiAL Sport 29mm QR BOV when swapping springs.

Product Details

This 2 PSI spring is made from a strong, corrosion-resistant stainless steel, designed to work specifically with TiAL Sport's 29mm QR blow-off valves. It's a well-built component that helps fine-tune your turbo system's performance by controlling when the blow-off valve opens. A lower spring pressure like this one means the valve will open sooner under boost, helping to vent excess pressure more effectively and reduce turbo lag.

TiAL Sport is known for making solid parts for forced induction setups. This spring is a direct replacement for the spring that comes standard in their 29mm QR BOV. Swapping it out is a straightforward way to adjust how your blow-off valve responds to boost pressure. If you're looking to dial in your turbo system for improved throttle response or to protect your turbo from over-pressurization, this spring is a practical choice.

Keep in mind that this part is not CARB approved and cannot be shipped to California. Always refer to your vehicle's specific turbo system requirements and local emissions regulations before installing aftermarket components.
