TiAL Sport QR BOV 8 PSI Spring - Black (34mm)

This is the TiAL Sport QR BOV 8 PSI Spring, designed for their 34mm blow-off valves. If you're running a turbocharged vehicle and want to fine-tune the boost pressure your blow-off valve (BOV) releases at, changing the spring is a common and effective way to do it. This particular spring is calibrated to release excess boost pressure when your system reaches 8 PSI.

TiAL Sport is well-known in the performance turbocharging world for making solid, reliable components. This spring is made from durable materials to ensure it holds its tension and performs consistently over time. Swapping out the spring is a straightforward process for anyone familiar with working on their turbo system, usually requiring just a few basic tools to access and replace the spring within the BOV housing. It’s a practical way to adjust your boost threshold without needing to modify the ECU or other engine management systems.

Keep in mind that this part is not CARB approved and cannot be shipped to California. Ensure your vehicle's boost levels are compatible with an 8 PSI release point before installing this spring.
