Abstract
In one example, an air intake system is provided. The air intake system includes a first air inlet duct providing intake air to an engine intake conduit, the first air inlet duct including an opening positioned external to an engine compartment. The air intake system also includes a second air inlet duct positioned upstream of the engine intake conduit and external to the engine compartment, the second air inlet duct including a porous material spanning an opening in the second air inlet duct, the porous material having a plurality of defined openings sized to prevent snow from traveling therethrough and collect on the porous material thereby impeding airflow through the second air inlet duct during snowy and icy conditions.
