An air and water management system for a motor vehicle is disclosed. The system includes an air opening allowing air to enter the engine room on a side of the motor vehicle, an engine cover covering at least one component associated with the engine of the motor vehicle, a rib extending from a top side of the engine cover creating a gutter on the engine cover between the rib and a side of the engine room, a water channel formed integrally in the engine cover adjacent and laterally inward of and parallel to the rib and including a drain longitudinally to the rear of the motor vehicle at a rearward portion of the water channel. Air entering the air opening flows over the rib and into the engine room of the motor vehicle. The rib blocks debris that enters the air opening from flowing into the engine room.
