FWIW, I've had the same E3 spark plug in my 4K gas Onan for years. It has always started right up and runs with a smoother, less burdened sound than it did with Champion plugs.
As a side note, our Onan has a convenient knob right behind it's side door with a graduated scale on it for adjusting it's air/fuel mixture to match the altitude that you're camping at. I've never read in these forums of anyone paying attention to this adjustment on their built-in Onan generators.
