Nuke Performance offers a variety of interchangeable springs for the 50mm blow-off valve BOV50c depending on how you want your setup, ideal for any boost level and to address your specific needs.
The BOV50c has a "blue" spring pre-installed, and changing to another spring is very easy thanks to the three-bolt design.
Choose the BOV spring pressure based on your engine's vacuum level at idle when the engine is at ideal operating temperature. The boost is independent of the spring pressures and is exclusively related to the vacuum. The lowest rate spring (light gray) is specifically designed for superchargers and is not intended for use with turbochargers.
