Fully black anodized finish. It helps a lot when trying to maximize airflow through a filter to have a large filter area. But building a huge filter was impossible, it had to be small and very effective. this is where the Arlen Ness design artists got their start. Adding the inside surface area of ​​the air filter to the outside adds a huge amount of filter area. With the integrated radiused air inlet, this air cleaner exhibited some of the highest flow numbers Ness has ever tested. The final appearance gives the air filter a very small, customized and attractive appearance, which effectively sucks in air from all sides and also offers more legroom. The filter elements are made of synthetic material. They are water resistant, usually a rain sock is not necessary. The filters are reusable, just rinse and reinstall. No oiling is necessary. Note: The breather design has O-rings on the heads, passes through the backing plate, and is positioned inside the mouth of the throttle body/carburetor. this eliminates external vent pipes, so nothing will take away from the clean look. Note: Not compatible with 64mm stage 4 throttle body. Note: See 590444 for optional rain sock. Not usually required but can be used when desired in exceptional downpours. Note: See 590397 for replacement filter element with chrome trim ring or 590396 for filter element with black trim ring. 18-21 Softails; 17-21 Touring; 17-21 Trikes
