Update: PurolatorBOSS PBC35519 Perfect fit. I have been on the quest to find a replacement cabin air filter other than the factory one, specifically a carbon laden one to catch some odors before getting into the cab. So far I have found the OEM filter number which is FP88 (19N619). However, when trying to cross reference the number on frams site I get about 30 related filters with that number segment. As eager as I am... I cant buy them all to see which one fits. Some say they fit the mustang others the edge.. ect. I know the size of our filter is going to be exactly the same as one of these but which one is the hard part to narrow down. Anyone have any insight on the subject?
