Twin Air Honda Pre-Oiled Air Filter for Motocross & Enduro Bikes.
Twin Air filters, dual stage air filters, are constructed from two layers of high-flow, open-pore foam that are bonded together to provide maximum filtration and superior airflow. The coarse-foam outer shell with a fine-foam inner core, resulting in a one-piece design that permits continuous airflow.
Twin Air filters are slightly smaller than stock filters, to increase the air space around the filter for improved circulation. They are constructed using a special adhesive that is unaffected by repeated cleaning, harsh solvents or gasoline. Each filter contains a thick, greaseless, flat foam sealing ring that insures maximum contact with your airbox, acting as a breathable gasket. They are made to fit in stock airboxes.
