The air intake further includes a pre-chamber accessing the first chamber, separated therefrom by a cross wall and communicating therewith via an access duct crossing said wall, with an inlet end thereof arranged in the pre-chamber and an outlet end thereof arranged in the first chamber, the pre-chamber arranged on the front side with respect to a forward vehicle direction. The pre-chamber includes a front access mouth; and a diverting baffle interposed between the access mouth and the inlet end of the access duct.
