I replaced the cabin air filter in my Durango with the new Potauto filter I bought last fall, yeah yeah yeah I know, but it was cold in the garage this winter. The existing Fram had about 60,000 miles of run time on it and was pretty dirty. I made a note to myself to change at 50,000 next time. Again the Potauto was considerably less expensive than the Fram and I don't see anything wrong with the Potauto.
