At higher engine speeds of a motor vehicle spark-ignition engine the intake volume of combustion air increases. This increased air requirement produces a greater drop in pressure on the air filter, which has detrimental effects on the supply of combustion air to the engine. In order to compensate for this fall in pressure at higher speeds of travel, it is proposed to provide a component (4) with an air inlet opening widening in the shape of a funnel for the combustion air, which is connected by way of a hose connection (10) to the air intake pipe (2) of the air filter housing (1) and aligned with its inlet opening towards the oncoming air (12). A considerable reduction in the fuel consumption was noted. <IMAGE>
