When you jack up the car look underneath just in front of the rear passenger tire, tucked up there will be a small canister looking thing with a bracket. thats your filter. What you wanna do is loosen the two huge hoses on each end of the filter while its still mounted watch for leakinf gas when you loosen it. slowly take them off the loosen the bracket bolts holdings the filter in place. wala thats it just repeat in reverse order with the new filter. Check for leaks when your done. Have Fun!
