TiAL Sport QR BOV 8 PSI Spring - Purple (1.5in)

This purple spring is rated for 8 PSI of boost pressure and is designed to fit the TiAL Sport QR blow-off valve with a 1.5-inch inlet. The spring's tension is what keeps the blow-off valve sealed against manifold pressure when the throttle is closed, preventing boost leaks. When you let off the gas, the vacuum in the intake manifold overcomes the spring tension, allowing the valve to open and vent excess boost pressure.

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 and reliability in your forced induction setup. Choosing the correct spring rate is crucial for proper blow-off valve operation; too weak and you'll leak boost, too strong and the valve might not open quickly enough. This 8 PSI spring is a popular choice for many street-driven turbocharged vehicles looking for a specific boost threshold.

Remember, this spring is not CARB approved and cannot be shipped to California. Always ensure you are selecting the correct spring rate for your turbo system's target boost pressure to maintain optimal performance and prevent potential issues.
