The BD7317 is used by Cummins 5.9 guys to replace the factory filter, And it's no different than the filters you would find in many 4cly turbo diesels overseas except it's has the Venturi feature for better flow and pressure.
This will give you a better ideal on how they flow. The LF9028 is the direct cross for it and I did happen to pick up a few from filterbarn for around 23 bucks each, these are even better due to their stacked disk.
