I just changed mine this past weekend. I picked up an oil filter wrench like this one:
Pennzoil 19902 - Filter Wrench | O'Reilly Auto Parts
at Oriellys auto parts for 6 bucks. Without it, I could not have gotten the little bugger out of there. Absolutely NO room to work with in there. Went 6740 miles before it told me to change the oil.
