I recently decided to protest a pricey air filter in Kioti packaging by using the cross reference numbers on this forum.I got a Napa #6489.It was their only available "gold" version but still it was about $10 less than the Kioti packaged Donaldson #p822768. They appear physically identical except for the gasket ring on the closed end,which is thicker, and it was somewhat harder to fasten the air breather case snaps. Anyone out there having similar experiences with their air filters? Eldon
