About K&N
K&N is the filter brand many Harley and Indian riders reach for when they want a washable, high-flow element in place of a paper one. This page lists K&N's range in the catalog, covering air filters, oil filters and the cleaning products used to look after them.
Air and crankcase filters
Air filters make up most of the list. They include HD-4915 for Street models, HD-0900 for Sportster, HD-1717 for Milwaukee-Eight Touring, HD-1499 for Touring and Softail and E-3226 for V-twin applications. Crankcase vent filters with chrome tops fit direct mount and clamp mount setups. Each element is shaped for a specific air cleaner housing, so the model code in the title matters.
Oil filters and care
Chrome oil filters are listed for Touring, Softail, Dyna, Sportster and V-Rod, and the chemicals group includes filter cleaner and oil used to re-oil washable elements. Following the cleaning interval from the maker keeps airflow consistent.
Fitment and tuning
Match the filter code to your bike and year, and avoid over-oiling a cotton element, since excess oil can foul sensors. A freer-flowing filter changes airflow slightly, so a fuel-injected bike may benefit from a tune afterward, and intake upgrades are meant for off-road and closed-course use.
