This is a factory original Honda air filter box intake plenum chamber designed to mount behind the carburetors. Made from durable, heat-resistant molded composite plastic, it works as an air silencer and stabilizing chamber for the intake system. Built-in rubber boots connect directly to the carburetor intake throats, while the factory brackets and offset profile provide frame clearance and sealed, balanced airflow.
