GM has used basically the same screw on (single) filter body since 2001. But the internals have been upgraded numerous times. The consensous opinion is that the GM is now a 2 micron filter.
What is fact is that it is made by RACOR and contains their exclusive "aquablock" membrane. GM is very proud of it's water blocking abilities....Though I do think water can get thru under the right circumstances. The latest GM filter is backwards compatible with all previous years Duramaxes.
Let me guess, the new GM part have superseded previous part numbers, and the older one is no longer available.
As in, you cannot buy the old style GM filter without the Aquablock membrane.
Me think there was a spec / design change.. and someone at GM said "oppsie daisy".
As for Ford.... read the SAE etc. articles on filtration, and clearly where there are publications, there is fire.
