Just looking at the prefilter on there websight. Its the little blue bag type thing that goes over the airfilter so u can just take it off shake it and put it back on so ur filter never really needs to be cleaned. I know they say offroad and racing use but has anyone tryed it on a street application. I feel like it might be a good investment.
