The Twin Air Air Filter, manufacturer part number 150901 and vendor part number 715-0901, is designed to provide dependable engine air filtration for select Honda three-wheelers. This foam filter uses a thick, flat, greaseless sealing ring that maintains maximum contact with the airbox while functioning as a breathable gasket for improved air passage. Its slightly smaller profile helps increase air space and circulation around the filter.
The filter features a coarse open-pore foam layer that captures airborne dirt, grime, and sand before they reach the engine. A fine open-pore inner foam layer provides secondary filtration for smaller particles while supporting efficient airflow. Twin Air’s specially formulated adhesive is designed to withstand repeated cleaning, including exposure to harsh solvents or gasoline, helping support long-term serviceability.
Fitment includes the 1985–1987 Honda ATC250ES Big Red, the 1985–1987 Honda ATC250SX, and the 1985–1986 Honda ATC250R. Verify the model and year of your Honda vehicle before ordering to confirm proper airbox fitment. The Twin Air brand and 150901 manufacturer part number are molded into this replacement air filter’s application details for reliable identification.
