Abstract
An air intake manifold for providing air from an exterior of a vehicle to a ventilation system of the vehicle. A primary plenum chamber has an intake passageway formed therein. The intake passageway is adapted to allow air from the exterior of the vehicle to enter the primary plenum chamber. A secondary plenum chamber is located within the primary plenum chamber. A shield is attached to the primary plenum chamber and extends over the secondary plenum chamber. A secondary inlet passageway is formed in an upper portion of the secondary plenum chamber. The secondary inlet passageway fluidly connects the primary plenum chamber to the secondary plenum chamber. A filter member covers the secondary inlet passageway to prevent debris from entering the secondary plenum chamber via the secondary inlet passageway. An outlet passageway is formed in the secondary plenum chamber. The outlet passageway fluidly connects the secondary plenum chamber to the ventilation system. A primary drain passageway is formed in a lower portion of the primary plenum chamber. A secondary drain passageway is formed in a lower portion of the secondary plenum chamber to fluidly connect the secondary plenum chamber to the primary plenum chamber.
