As for the oil filter, it is much more difficult to get to than any car I have owned although once you do it once, it is very easy. To get to it you have to remove the air filter cover, disconnect the hose that goes from the bumper to the airbox, and then lift out the air box with the entire engine cover(It comes out in one huge piece). The airbox and cover are held in place with rubber grommets so there is no unscrewing to do. Just pull it hard and the whole piece comes out.
Once you get the air box out you will see the filter cannister. Remove the cover by removing the center bolt and then pry off the cover. Remember to replace the gaskets(2) in the lid of the cannister with new ones that should be supplied with your new filter element.
To access the oil drain plug, you will need to remove the bottom engine cover behind the bumper by removing four small bolts. You will see the oil drain plug on the passenger side of the oil pan. Replace the oil plug washer with a new copper crush washer.
Good Luck
