The air intake channel (16) has a channel section (20) within a channel body (18), for the cylinders (12) of an internal combustion motor, with a tumble flap (22) on a tangential rotary axis (24) to give a tumble air flow into the cylinders. The tumble flap can close 80-20% of the channel cross section surface according to the channel design.
