The Twin Air Air Filter, manufacturer part number 150201 and vendor part number 715-0201, is designed for reliable filtration and airflow on 1978–1981 Honda CR250R motorcycles. Its thick, flat foam sealing ring provides broad contact with the airbox while functioning as a breathable gasket to support efficient air passage.
The filter uses a dual-layer open-pore foam construction. The coarse outer foam captures airborne dirt, grime, and sand, while the fine inner foam provides a second stage of filtration for smaller particles. This design helps protect the engine from contaminants without unnecessarily restricting airflow. The filter is slightly smaller than the original equipment filter to promote additional air space and improved circulation around the filter element.
An exclusively formulated adhesive helps the foam layers maintain their bond through repeated cleaning, including cleaning with harsh solvents or gasoline when used according to proper service procedures. The greaseless sealing design simplifies installation and helps create a dependable seal against the airbox.
Fitment: Fits 1978 Honda CR250R, 1979 Honda CR250R, 1980 Honda CR250R, and 1981 Honda CR250R. Always compare the existing filter and airbox configuration before installation to confirm application compatibility.
