John,
I once owned a filter manufacturing division for our Warehouse Distributing Company. We manufactured under four names for our customers in the auto parts stores, mower dealers, motorcycle dealers, trucking, you name it. When we retired, we sold the company to a big company that was always trying to put us out of business. We even manufactured for them on a couple of occasions.
Kawasaki does not manufacture oil, hydraulic, air of fuel filters. They purchase them and a company like ours were under contract to ink their names, filter number and patent dates on each filter, along with any warnings, etc. Same for the filter boxes and case boxes that the filters were delivered to them in. Our company didn't make the cardboard boxes so we contracted out the boxes as well as the printing. At the very end, we invested in a printer that printed the boxes for a huge savings in production costs.
My point to all this is: Ford Motor Company, General Motors, Chrysler Motor Company, John Deere, Kia, Toyota, none of the motor companies makes a single filter of any kind. If you would like a filter brand, it is very simple, get in touch with any filter manufacturer out there and they'll give you a quote for the filters of your specifications. I don't know any that will manufacture a filter with a lower specification than the motor manufacturer.
The answer to your question is: You can use any brand filter that meets or exceeds the motor manufacturer's specifications. There has been hundreds in not thousands of lawsuits lost by motor manufacturers for trying to withhold warranty service or replacement due to items purchased and used without their company name on them.
I always look forward to a dealer trying that on me. Even though I'm twice retired, I might not mind owning another manufacturing company.
Good luck,
Max
