The AMSOIL EaO filters originally had Donaldson Synteq media in them, they cheaped out a few years ago and moved the whole can to Champ.
Fleetguard has a range of medias, the most recent I think is an updated version of Nanonet, but they went from microglass to Stratapore, which was a media that was laid in continuous strands with no breaks, and was a polymer, so didn't need the same bonding agent as microglass, to an evolution of that process with Nanonet.
There are a few part #'s that cross to passenger car/light truck applications with the Stratapore media, including the Ford FL-820S equivalent, which fits many/most of the HEMI applications (and is the spec SRT filter).
