Designed to fit the factory air box just like the original filter. Dual layer filters come apart for maximum air flow and ultimate cleaning. Clean easily with grease cutting detergent; just clean, oil and reuse indefinitely. Large pore pre-filter catches bigger particles, while the small pore inner filter prevents any engine-wrecking grit from reaching the cylinder. Most filters feature the Ultra Seal with “Grease Lock” on the sealing surface.
