Wix filters are available as some chain stores, and are at least as good as the OEM one (they actually have a wound cord fine filter instead of packed gin trash, for instance). The o-ring supplied is too large, but you can get one at a dealer or bearing supply.

Otherwise, OEM only, these engines are MUCH to expensive to rebuild to trash by using cheapo filters.
