Arlen Ness Air Intake

Arlen Ness air intake hardware is the dress-up piece a Harley-Davidson custom build wears on its right side, where everyone walking past the bike sees it first. The company has been doing this since 1970, when Arlen Darryl Ness machined his first billet parts in a San Leandro garage on his own Knucklehead, and the air cleaner became one of the brand's signature canvases — wide enough to shape, visible enough to matter, structural enough to do real work. Today, run from Dublin, California, by Arlen's son Cory Ness, the catalogue covers billet aluminium air cleaner assemblies, matching covers, and breather kits cut for Sportster XL, Twin Cam, and Milwaukee-Eight intake setups, with options for both stock-throttle and electronic throttle bodies. Each piece is finished to show standard rather than parts-bin standard. Iron City Motorcycles, an authorised Harley-Davidson dealer in Leeds, stocks Arlen Ness for Softail, Dyna, and Big Twin owners who treat the right side of the engine as a styling decision.
