Was going through my service manual and got to the part about air filters. It says some models have an in line breather filter and a foam breather filter in the air box. This in on a 99 sportsman 500 by the way. I'm not talking about the round air filter and pre filter either. Anyway, mine doesn't have the foam pre filter for the rubber hose connected the the left side of the air box that goes to the engine. It does have the in line filter. The part I don't understand is it says some models have both and some have the foam. Then below it says never operate the engine without the foam prefilter. This info is on page 2.45 of the Polaris service manual for 99 models.

Does everyone else have the inline and the foam prefilter?
