Lol, what an odd thing to do!! The benefit will be that it sounds cool I guess! Either that, or it had a cone filter that has fallen off somewhere.
The downside will be that it's sucking in all sorts of crap, so really not a good idea lol. Should just need the housing, filter and any piping that has also been removed.
