Very nice filter!
Internals look to copy a Fram Ultra, with the exception of the louvers and the spring.
I like!
It does look similar. Perhaps Fram copied Donaldson to a minor degree? It's the best form of flattery...The Donaldson Synteq media has been around longer than the FRAM Ultra, I believe by a pretty wide margin.

I posted some excerpts from a Fleetguard paper on it quite a while back now, but the idea was that the depth filtration media, when compared to surface filtration (cellulose) allowed for superior filtration performance and higher contaminant holding capacity all while improving flow.
