Uni Filter Inc. Parts & Accessories

Uni Filter pioneered the dual-stage foam air filter back in 1969 and have collected more Supercross championships in the years since than any rival filter brand. The principle is open-cell polyurethane foam soaked in tacky oil — dirt sticks to the foam strands while the filter still flows strong air.

For Harley owners chasing cleaner induction without committing to a full air-cleaner conversion, the washable foam elements and pod filters are reusable, easy to service, and stand up properly to UK weather, dust, and salt. Long service life if you actually clean and re-oil them.
