Fortunately on the 7th Gen, they fixed the mounting system and it can be changed in 2 minutes or less (most time is spent cleaning out my junk in the glove box). I am a little annoyed that the filter was $24 at the dealer. I think I'll also put together a DIY solution. I also think a good 3M filter from Home Depot cut to fit should work perfect. A $8 10x20 filter should make 2 replacements.
