The aFe Magnum FORCE replacement air filter with part number AFE21-91145 is engineered to deliver reliable filtration performance for your vehicle's intake system. Featuring three layers of oil-free synthetic media, this filter provides excellent dust-holding capacity and filtration efficiency without the need for oil during maintenance, ensuring a clean and hassle-free service. Its progressive layering design increases surface area and enhances dust retention, making it suitable for street driving and light off-road applications. The inverted top design maximizes filter surface area, allowing longer service intervals and consistent airflow. Constructed with a durable polyurethane frame, this filter maintains its shape through repeated heat cycles, ensuring lasting performance even in demanding engine bay conditions. The rounded, evenly spaced pleats optimize the usable filter surface, translating to increased airflow and superior dust filtration, which contributes to improved engine health and efficiency.
