This genuine OEM air filter box housing is made from durable injection-molded polypropylene plastic. It forms the central intake housing, protects the air filter element from dirt and debris, regulates airflow, and helps reduce intake noise. The base features two rubber intake boots designed to fit directly over the twin Keihin carburetor inlets. The side casing carries the factory molded identifier “KH 4038.” This airbox supports the correct factory air-to-fuel balance for smooth idling, throttle response, and reliable engine performance.
