ozzielad, how did you go with this? I have a 2006 and cannot imagine the cover being much different?. For my 2006 once all the visible screws are removed including the two near the strut brace, pop the cover up near the oil filler then slide forward. ie I have no screws under the pollen filter assembly. I admit it is a pain to seat the cover when replacing it - you have to position the tangs on the rear of the cover back in the slots under the pollen filter assembly but a torch helps. Once done then a push down to seat the clip near the oil filler and 4 bolts and done.
