GBurton, In my 2001 the filter's are stacked. The bottom one came right out no problem. I had to get a mirror and flashlight to look up there to even see the other one. I tried with a long screw driver to get it but no luck.

It sounds kind of weird to me that they would put 2 filters in "series" as you have described. but, who know how some design engineers think.

I still could use some advise on how others are removing the upper filter without going insane.
