Here's what you need: Just scroll down till you see air filter removal only. Repeat process on other side.
Thanks, after I do the air filters, the next task is to replace the power antenna. I have a convertable and I am wondering if I can get to the antenna from the rear wheel well rather than pulling the convertable top hydrolic pump from the trunk.
