Description 

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.
