ABSTRACT:
The invention relates to a device with an air inlet manifold (1) and an air mass sensor arrangement (2) inserted radially therein, the insertion opening (3) of which is arranged perpendicular to the airflow direction (6) in the manifold (1). A wing-shaped shielding body (7) is arranged before the insertion opening (3) such as to cover the insertion opening (3) and guarantee a streamline airflow to the insertion opening (3) and the essentially straight surface thereof, transverse to the flow direction of the air flowing over said surface, is oriented perpendicular to the insertion direction of the air mass sensor arrangement (2).
