Motul A1 Air Filter Clean is a specialized cleaner designed for reusable foam air filters used in motorcycles, quads, and off-road machines. The formulation is engineered to dissolve and lift out trapped dirt, oil, grime, and fine particles without damaging the foam structure. Because it dries fast, it minimizes how long your machine is off the road during maintenance. After applying A1, the filter is rinsed with water, allowed to dry, and then re-impregnated with Motul Air Filter Oil before reinstalling. This cycle ensures the filter retains both its filtering effectiveness and airflow performance.
