When I replaced my in-take manifold gasket, before being able to remove in-take manifold to replace gasket,
There was nine nuts holding it onto the engine. Easy enough to take off considering I live in the rust belt.
Then there were these two things which I thought were engine grounding straps
Guess they were more like supports (as seen in your photo)
Anyway, the two bolts were the hardest to take off the in-take manifold.
