You access it from the Glovebox area.
There are 2 stops on the glovebox door that you push outward to let the glovebox door swing all the way down. You then have 3 tabs to pull down to release on the filter door. Then slide the old one out. Put the new one in with the air flow arrow pointing in the right direction (Pointing down)
Easy to do.
That was easy, but it was absolutely filthy 55k never been changed. I couldn't get a new one today so I vacuumed off the top of the filter and blew it out but it's not clean by any means. I'll get a new one this week.
