WHO CARES The truth is way to many people on this and many other sites spend way to much energy worrying about the damm oil filter. Truth be toll, there are only a hand full of filter manufacturers in the country, and they simply supply many, many different BRAND NAMES with the same filter, just a different color, name or some other identifying mark. All filters made have to follow the specifications laid down by the engine manufacturer (in our case Cummins), these specifications deal with the physical dimensions and characteristics of the filter. Like filter Thread size and Pitch, relief pressure setting and so on. The filter media is of-coarse different on some brands, but it still has to meet the specific criteria the engine manufacturer spelled out. I would much rather see someone stop obsessing over one brand of filter verses another brand while all the time running extended oil drain intervals and not replacing the filter, and buy a cheaper but still spec filter and change it on a more timely bassis. With the advent of much better oils and synthetic oils, the oil it self is not the problem. The problem is keeping that oil clean.
