The oily crap comes from over filling the oil or from excessive gases getting past the rings and pressurising the crankcase causing oil to get pushed into the airbox.  There's a pretty big kink in that breather too so it'll get blocked quick enough and then the lovely mayo builds up from water vapour not being able to get through the breather. That's my theory anyway and I'm sticking to it :lol

Now you see you have got alot of big words there and so im convinced

What like crankcase? That's not big and I think it might be two words :lol I thought we'd done the k&n debate before and someone had dynographs showing there was no increase in power but that it  gave a better power curve so you get better mid range whatever that means :lol I haveone because you can clean it and reuse it. If you don't have one I don't think you're losing out anything really
