    Hope someone can shed some light on this for me. I just called my local Hustler dealer for pricing on an Air Filter for a 23hp Kaw. Z (8yrs old).....he said the inner is $x and the outer is $y. I replaced the original filter once before and it did not have an inner/outer combo on the filter or did I have inner/outer on the replacement filter??? He stuck to his guns and said you need both. Here's where it gets even more interesting, the Kaw manual shows some sort of foam slip on over the paper element, but the Hustler manual calls for a Donaldson filter (part 785261) which has no slip over outer element. Can someone tell me which is correct and maybe even a link to the correct filter.

    I would get the best air filtration system available. I would need more numbers of your machine and engine to tell you what was stock for your machine.

    If your system has a pre-filter (foam slip over), they are very cheap. I keep several of them and change them every couple of weeks washing the one I replace. They are to cheap not to do this and you will see a big improvement in the life of your paper filter.

    I bet they came single, double and with the pre filter.

    Kaw engine, Donaldson Air Filter in manual. Large cannister filter, no inner was removed.

    I am beginnig to think this was an engineering change AFTER my model.

    Eight years old puts you about 2005, 2005 IIRC used only the outer. Putting an inner on it will make it run rich, restricting more air. kawasaki used different jets on each cylinder to account for the difference in runner length. The new FX series engines have gone back to an inner and outer. I was concerned that you did'nt have the cannister filter (older units did'nt) because there is a filter for internally vented carbs and externally vented carbs. Mess them up and your engine won't be happy. That's not a concern with the cannister style filter.
