Anyone been able to find out the efficiency (micron ratings, cfm air flow, etc) of this filter yet?? I notice there are a few different filters which all cross ref the same part number (NAPA, Baldwin, Wix, Fleetguard/Cummins) Anyone know if the filtering ability is the same between the different brands??
A very early post mentioned Fleetguard has a few different filter medias. I assume this filter is probably just "basic" filter media. The post said the part number for the filter in this topic did not cross reference to Fleetguard's better filter media filters. How about a filter with similar dimensions made from Fleetguard's better media? Might entail some time looking through a Fleetguard catalog comparing the filter dimensions. Sounds like a good research project, any takers?
