I'm in the process of installing my MP and just found that the C&L plenum doesn't clear the snout. Anyone else have to grind the TB flange &/or the snout to use these two parts together?
Well here's some pics of the grinding and clearance when used without a spacer.

As you can see, without grinding the plenum would never have sealed to the blower without a spacer. At least it's on and sounding good. Too bad it's -15* and very icy outside.
