Used to, you could get FL1A's at Wal Mart dirt cheap. They never have them anymore. If they haven't changed in the last little bit, Mann & Hummel still makes Wix filters in Gastonia, NC.
WIX went global several years ago, before I left O'Reilly in 2019. Now, you might get one made in USA, Belgium, China, Indonesia and Lord knows where else. Sad, really.
