I really Doubt New Holland makes their own Filters . On another board , It was reported that filter shipments to their New Holland Dealership were in Fleetguard boxes yet the actual filter had the typical New Holland markings . It is a lot cheaper for a company like New Holland to pay a filter maker to stamp their name on a product than to have all that equipment themselves . Same likely can be said for Onan , Motorcraft , etc.... . I've Seen one company package one item in 8 different packages , each package marked with a specific brand and then sold at the various brand stores at remarkably different prices , yet all the same product inside .
My experience with New Holland's warranty is it is not worth much more than the paper it is wrote on , It actually boils down to how good a local dealer you have , not the Actual maker . If your local dealer goes to bat for you , it can make a world of difference , while a less worthy dealer does not help at all .
Myself , I've used Wix Filters on everything for quite some time now . Never have had any issue's including a old '84 ford f250 with 150,000+ original miles and the 460 engine still keeps purring along , with very little oil use , ( does need a new clutch but that is another issue !!! ) .
Wix makes virtually all the Napa Filters .
