K&N Crankcase Vent Filter are designed to push onto the crank case of an engine or be used for catch cans and a number of other things. You could even use it if your a painter and sander... Put it in your mouth with a rubber pipe and breath through it all day while you work ( Bit of a laugh - but it works!!! lol ) Ideal for engines, transmissions, oil or gas tanks on racing vehicles.
