If you look at the specs, those Cummins power units are low-rev, industrial-grade engines which are typically producing 60HP to as low as 20HP.
Using the oil filter meant for the Cummins in a high-revving or even a turbo-charged engine might not be a good idea.
Maintaining the correct oil pressure in the engine is a balance between having the correct oil viscosity, oil pump pressure, engine tolerances, and the filter media, among a few other factors (ie. temperature, RPM, etc.) That said, too little pressure from an overly-constricted filter media can starve a high-revving engine of oil. But the most likelihood that will happen is that, everytime you rev up, the oil might just go through the bypass valve, unfiltered.
Of course, these are all conjecture but then again, it's better to use parts that are specifically designed for your engine rather than use one that you might perceive to be better without knowing all the details.
