Hey what's up? I'm 3/4 way through installing a supercharger in my 99 SH model. I've talked to about a million different people (including Jackson Racing) and no one seems to know where the Intake Control Solenoid Check Valve is located on my car. I don't have the stock intake box on the car anymore (replaced w/Injen cold air). Can anybody please help me?

 

It was probably removed when the Injen intake was installed. That check valve is on the line that runs from the intake control solenoid valve to the intake manifold.

In any case, this is much worry over nothing. If you've got an aftermarket intake then this check valve has nothing to do with your JRSC install.
