I did a search but couldn't find the info I am interested in? My 02 RKC has the stage II kit 29775.02... Does anyone know if this filter is washable and then require oil? The filter only has markings on the front which say FOR HD TWIN CAM ONLY and stamped in the black gasket around the larger portion of the filter is a code of A063A4..... This is the filter that came with the stage II kit way back in 2002.....Anybody have any clue about this filter???

Thanks!
