Reusable Foam Air Filter

Description

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.
