I also picked up the FRAM CF11173. I must say, at first glance, I thought I bought the wrong filter. When I pulled the cover off, I thought no way the things was going to fit. I had to wrestle the old filter out (luckily it wasn’t too dirty) and it was completely deformed when I got it out. I then had to accordion and bend the new filter to get it into the slot. The slot is probably 70% the size of the filter. Probably the strangest design decision of this van. Anyway, I think I got it in there, air smells nice and fresh.
