Seems to me like something should go here....
All,

This hole is in the underside of the passenger side inlet plenum. I can't imagine that this hole is supposed to be there with nothing to fit in it, but I don't see anything dangling about that should be (or looks as if it needs to be) connected up.

Can anyone help me out here? Should I put a solid grommet in there??

Thanks in advance,

Brad
