High-Flow Washable Air Filter Element For 2004-2013 Harley Sportster #29331-04

Cycle Standard air filter elements are washable and reusable. The filters are constructed of two sheets of aluminum wire mesh containing multiple sheets of cotton gauze. To increase the filtering capacity and performance the filters are oiled. The result is a filter that achieves high, almost unrestricted air flow while providing filtration levels needed to ensure long engine life. See Additional Information below for fitment.
