10. Single Inlet Restrictors
a. The intent of this rule is to have a sealed system from
the Restrictor to the Intake Ports of the Cylinder Head.
All of the air entering the Intake Ports shall pass through
the specified Restrictor.

Does this mean I need to disconenct and plug my idle air valve? It pushes air right into the manifold, after the throttle. Or am I misunderstanding the meaning of "intake port"?

No, it just means the supply to the IAV must come from downstream of the restrictor. ;)

That's the way I read it.

Hmm, and I guess it must, since the idle valve wouldn't be suckin' unfiltered air, right? Thanks for the help!
