The nozzle element is located within the inner opening of the air cleaner's tubular filter element. The perforated portion is arranged and configured to be the same size and shape as the inner opening to provide support for the tubular filter element, the throat is arranged and configured to provide the required restriction to create a specified negative engine crankcase pressure, and the noise suppressing portion is arranged and configured to provide the required attenuation of engine intake noise passing through the air cleaner.
