The aFe MagnumSHIELD pre-filter (black) protects performance air filters by removing large particles ahead of the primary media, extending service intervals without airflow restriction. Its dry weave fabric cleans with soap and water and resists dirt cling. The pre-filter slips over compatible aFe filters and is intended for use with SKUs ending in XX-91051, backed by a two-year limited warranty.
