The Twin Air Air Filter, manufacturer part number 150004 and vendor part number 715-0004, is designed for dependable air filtration and improved airflow in select Honda two-stroke motorcycles. This replacement foam filter fits the 1996–2002 Honda CR80RB Expert and the 2003–2005 Honda CR85R, providing a precise fit for the original airbox.
The filter uses a dual-layer, open-pore foam construction to capture airborne dirt, grime, and sand without unnecessarily restricting air passage. The coarse outer foam traps larger contaminants, while the fine inner foam helps capture smaller particles before they reach the engine. Its thick, flat sealing ring forms broad contact with the airbox and functions as a breathable gasket for reliable sealing and consistent intake flow.
Twin Air designed this filter slightly smaller than the stock filter to create additional air space around the element and promote circulation inside the airbox. An exclusively formulated adhesive withstands repeated cleaning, including cleaning with harsh solvents or gasoline, helping support long-term serviceability. The greaseless sealing design simplifies installation while maintaining dependable contact with the airbox.
Install this Twin Air filter as a replacement for a worn or contaminated original filter on compatible Honda models. Proper maintenance and cleaning should follow the manufacturer’s recommended procedures to preserve filtration performance and protect the engine from abrasive particles.
