Bolt the throttle body onto the new supercharger using two new gaskets to sandwich the bracket that will be used to hold the throttle linkage. We used a throttle-body spacer on this installation to provide clearance for the idle air control (IAC). Set the supercharger in place just to check clearances. Once everything lines up the way you want it to, take the supercharger off, put a thin film of RTV silicone on the mounting plate, and install the supercharger assembly. You will need a short 10mm wrench to tighten the bolts that come up through the bottom of the manifold plate into the supercharger.
