The specially designed pleated media on each filter piece provides less restriction than typical foam air filters. Allowing your engine to breathe easier can give your Honda extra horsepower and acceleration while providing excellent filtration.
The epoxy coated aluminum wire mesh incorporated into a backfire screen, protects the filter element from harmful debris. This two-piece design makes installation and removal easier for HA-4509XD, HA-4503XD and HA-2505XD on narrow MX bikes. Pliable application specific sealing beads ensure an air tight fit against the backing plate.
