Forge Universal 50mm Black Blow Off Valve
We recommend the option Blue Spring + 6.3mm Shim (-10 PSI) for most N54 application, unless you have measured your vacuum pressure reading and are producing much more or much less than than 10psi, this should be taken at normal operating temperature whilst the engine is idling with a pressure gauge for accuracy.
In The Box
1x Clamp-on Boss
1x V-Band Clamp
1x Forge Motorsport Key Ring
*The picture above illustrates the valve assembly, please note that only one shim can be used and how the shim fits between the piston and the spring*
