The air intake is one thing, and can be taken care of fairly easily, but I am curious about your PCV valve? I think that I see the clip that holds the tube onto the PCV valve tucked under the plastic engine cover (in the second photo above), but I don't see the tube going to it and the engine cover is cut up in that location.

I don't think that it will cause too much of a problem for the engine (I'm sure that I have driven around with mine completely clogged and not working), but it might be something to look at.
