Back in 2012 Fleetguard put out a press release on some spin-on NanoNet filters, which is the same 3um media used on the 2010+ OEM filters. From what I can tell it is one of the best filters available...

Anyhow after 3 years of calling my local Cummins to get the filters they finally got them in stock. 

The FF5814 is the replacement for the Donaldson P551313 or Cat 1R-0750 that many of us use. 

3um at 98.7% 
99.6 GPH
74.82gr dirt holding capacity. 
One brochure had 4um at a Beta 200, which is 99.5%. 

The ISO standard used is multipass vs the older single-pass but it appears that OEM's are starting to ask for the multi-pass ratings and not single-pass anymore. 

I bought two today, one for me and one for dad's 06.

I remember about 7-8 years ago sitting through a fleetgaurd filter presentation class and this was top secret technology then, they talked about it but didn't want to give out too much at that time.

Some more reading material on the subject from Cummins.
