Air Cleaner Kits

Harley-Davidson air cleaner kits manage the air entering the motorcycle's carburetor or electronic fuel injection system while combining the filter element, backing plate, breather hardware, cover and related mounting components into a matched intake assembly. This category includes Harley-Davidson high-flow air cleaner kits, Stage 1 and Stage 2 systems, complete performance air cleaners, replacement filter kits and model-specific intake assemblies from manufacturers such as Arlen Ness, S&S Cycle, Vance & Hines, Feuling, Cobra, K&N, V-Twin, Trask, Kodlin and Performance Machine. Harley-Davidson service documentation shows that air cleaner assemblies can include a backplate, gasket, breather components, mounting hardware, filter element, cover and rain sock depending on the kit.

The product range covers different intake styles and configurations, including Harley-Davidson high-flow air filters, Big Sucker systems, Heavy Breather-style designs, teardrop and oval air cleaners, velocity stacks, backing plates, breather kits, air cleaner covers, support brackets, adapters and replacement hardware. Carbureted applications include components for CV, Linkert, Bendix and other intake configurations, while EFI applications cover Twin Cam, Sportster, Softail, Touring and Milwaukee-Eight motorcycles. Replacement filters and pre-filters are also represented, along with rain socks and related filter protection. Harley-Davidson documentation identifies filter elements, mounting plates, intake tubes, gaskets, breather plugs and rain socks as service components used across different air cleaner designs.

Harley-Davidson air cleaner kits cover a wide range of intake configurations for carbureted and fuel-injected motorcycles, including Evolution, Sportster, Dyna, Softail, Touring, Twin Cam and Milwaukee-Eight applications.
