A fresh air duct system for a vehicle that includes an engine air cleaner with an attached conduit for passing fresh air into the air cleaner. The system includes a bumper beam that has elongated upper and lower air passageways that can be in fluid flow communication with the conduit for defining an air flow path between the air cleaner and the passageways. Fresh air can be introduced into the air duct system such that at least one of the air flow passageways can simultaneously act as a sound resonator and a resonator tuner.

[ What is claimed is:] [1.] A fresh air duct system for a vehicle that includes an air cleaner with an attached inlet conduit having an opening for passing fresh air into the air cleaner, the vehicle including a bumper mounted thereon and the system comprising:an elongated beam contained in the bumper and having an upper air passageway and a lower air passageway, the upper air passageway being defined by an elongated upper wall, an elongated cross-member, and axially opposed first and second end caps each attached to the upper wall and the cross-member, the lower air passageway being defined by the cross-member, an elongated lower wall, and axially opposed first and second end caps each attached to the lower wall and the cross-member, an outlet aperture disposed in the upper passageway, and a connecting opening between the passageways disposed in the cross-member adjacent to the first end caps;a bumper abutment plate, to which the beam is secured, having an aperture extending therethrough in axial alignment with the aperture disposed in the upper passageway, the conduit opening being in serial fluid communication with the aperture in the abutment plate and the upper passageway aperture for defining an air flow path between the air cleaner and the upper passageway; andwherein fresh air is introduced into the air duct system through an opening in the second end cap of the lower passageway, travels the length of the lower passageway, passes through the passageway connection opening, and then travels the length of the upper passageway before entering the conduit and the attached air cleaner.
