I had the same problem with my car. I don't know if it is the same or not because mine is a 2004. Anyways I finally found where it is located by looking at the owners book that came with the car. On my engine it is on the top driver side. You have to remove the plastic cover on top of the engine. once that is gone looking down into the engine, and you will see a round black lid with a nub that sticks up that you fit a socket onto. If I remember correctly the socket size is either 1 1/4 or 1 1/2. Once you get that loose be careful not to spill oil all over as you pull filter out, as well there is an o-ring on that black lid it is recommended that be changed as well I think. I didn't replace it on mine and I've had no problem. I hope this is in some way helpful to everyone.
