The thin air channel will not mesh well with tets -- especially with tets the sizing it is trying there. The body looks simple enough to sweep/multizone, but I would cut it up further so that you could have a resolved mesh where the inlet come in.

As for the piping network, I would try and see if you could use multizone to mesh these. Then you could have more high aspect ratio hex elements to reduce your mesh count.
