An air-directing component (10) of a motor vehicle has an installation surface (18) that bears against an outer side (20) of the front end (12) of the motor vehicle. Hook-shaped projections (14.1, 14.2) protrude from the installation surface (18) and have dimensions which are matched to dimensions of the recesses (16.1, 16.2) in the front end (12) in such a manner that be pushed into recesses (16.1, 16.2) of a body front end (12) of the motor vehicle. Each projection (14.1, 14.2) reaches through the recess (16.1, 16.2) and engages behind an edge (26) of the recess (16.1, 16.2) on an inner side (28) of the front end (12). The shape and arrangement of the projections (14.1, 14.2) permit the projections (14.1, 14.2) to be pushed transversely with respect to a longitudinal axis of the motor vehicle into the recesses (16.1, 16.2).
