Just replaced the cabin air filter on my wife's 2007 base coupe. Used a Purolator from Advance Auto that cost about $23. Car only has 9632 miles on it, but what the heck. I think I'll do it as an annual type thing after the pollen has finished in late spring. We get a lot around here in Hampton Roads, VA. It was a different thickness from the stock filter so I was worried it wouldn't fit. It went in nicely. Instructions came with the filter but only said you need a screwdriver. No mention about a Torx T-15. Good thing I have a set. Awkward positioning too to work on it! Thanks to previous guys with info on the change and Andrew's pics.
