AHA V6 - 98 avant,

I want to pull the intake manifold so I can replace the knock sensors. (Had P-code for a bad one. ) Jeez, I'm stuck at the earliest step in that I can't see how the plastic intake is mounted.

I'm guessing it's a press fit into a rubber o-ring? I don't want to guess wrong and bust a mounting bracket though.

Any other tricks to getting the TB off, other than finessee?
