Arlen Ness Beveled Inverted Big Sucker Air Cleaner Kit

As far as we know, K&N doesn't produce an air filter that'll fit an Arlen Ness Inverted Air Cleaner. No less, you won't be required to buy a new filter when this one becomes soiled since it's washable and reusable. The element itself is composed of a synthetic filter material doesn't need oil. You can wash it with pretty much any solvent as required. Plus, the material is hydrophobic, so you don't need to use a rain sock on it, unlike a K&N air filter, when the roads get wet.
