A system for managing the air of a front-end air inlet of a motor vehicle may include at least one flap and a holding frame for holding the at least one flap. The flap may include a pivot pin for pivoting the flap. A support with at least one bearing may receive the pivot pin and a closing element for closing the bearing. A control device may control the movement of the flap between a sealed position in which the air inlet is sealed and at least one open position in which the air inlet is open by pivoting the pivot pin in a region of the bearing. The flap may include an actuating finger for actuating the flap, integral in movement with a rod controlled by the control device. The closing element forms a guide for the rod.
