An air inlet conduit for a cooler of a vehicle has an air conduction scoop inserted into an opening of a vehicle body skin part on its air inlet side. The air inlet conduit is supported by way of a surrounding collar section on an exterior side of the vehicle body skin part, a scoop section extending away from an outer collar section of the air conduction scoop, which scoop section projects into a hollow space of the vehicle body skin part situated behind the latter. The air conduction scoop is connected to an adjoining closed flow-through conduit. So that, during the mounting of the air conduction scoop and/or of the flow-through conduit without any gauge and independently of worker skills, a constant gap is always ensured between the air conduction scoop and the adjoining vehicle body skin part, several trim lugs, which are arranged in pairs on the edge of the opening and project into the opening, are provided. The trim lugs interact in a form-locking manner with positioning pins or positioning sections of the air conduction scoop and/or of the flow-through conduit.
