The BMC motorcycle air filter for the Honda TRX 400 EX, 1999 and later, is a free-flow filter designed to provide greater airflow than the original paper filters. The filter media is cotton gauze impregnated with low-viscosity oil, while the frame is manufactured using the Full Molding method as a single piece, with no welded joints at the corners.
The soft rubber molding helps prevent breakage at the corners. The epoxy-coated wire mesh protects against gasoline fumes and oxidation caused by moisture in the air.
