The K&N HD-0800 is a round tapered replacement air filter built on K&N's cotton gauze element, which the manufacturer markets as a high-flow, lifetime engine filter for Harley-Davidson Twin Cam Screamin' Eagle applications. Its 6.25-inch base and 5.5-inch top outside diameters and 2.125-inch height define the profile, and the manufacturer cross-references Harley-Davidson part 2944299D as the OEM equivalent. Because the element is washable and reusable, it trades the recurring cost of disposable filters for a periodic clean-and-re-oil routine.
Choose this over a stock element when you want a reusable intake filter you can service yourself. The manufacturer specifies a re-oiling amount of 0.37 oz (11 ml) per service. Fitment is the step to verify: sources disagree on which model years and models the HD-0800 covers, so confirm your exact year and model with the manufacturer before ordering. The element has no flanges and no inner wire, so measure your air cleaner housing against the stated diameters and height before you pull the old filter.
