I recently ordered the cabin air filters and decided to give it a try. Other than somewhat of a tight area to work in, changing the cabin filters did not take too long. I was surprised that it takes two filters rather than just one. They are pretty small. It requires that you remove the glovebox and remove a couple of components to gain access to the filter holders. I found myself pretty much on my knees with the door wide open trying to squezze into a reltatively tight area. It took me probably around 30 minutes to do it for the first time. I probably could have left the OEMs in place as they were not too dirty.
