Just did mine on 18 stx. Only need 7mm. Took all of 10 minutes apart and back, and I didn't read the how to.. At 38000km it was starting to smell dusty, and visibly it was due. Replaced with a fram fresh breeze from Amazon. Air flow arrow points down.
Finally got around to replacing my cabin filter this weekend. Took all of 10 minutes and only broke one of the clips that holds the upper glove box part in place. 15K miles and only driven a gravel rode once.
