A wheel-housing shell for incorporation in mudguards of a motor vehicle extends at least approximately parallel to the mudguard and over a considerable part of the inner periphery of the mudguard; the shell forms a hoselike channel having an air inlet at its end at the front in the driving direction and at its other end an air outlet directed towards the roadway, is improved in that the wheel-housing shell is equipped with orifices which assist and make easier the passage of water splashes into the channel; and such a wheel-housing shell is covered with a sound attenuating filter mat on the side of the respective shell facing the wheel and over the respective entire surface that extends parallel to the mudguard.
