Gunna revive an old thread,
This your friendly reminder to change your cabin filter. My car has 45k miles and this is what the filter looked like when I pulled it out today.
It's super easy if you watch the tutorials on youtube a time or two before. I found a, I believe it was, 9/16 socket to work the best for the screws. All in all it took me 20 minutes start to finish. Just take your time.
