Abstract
An engine air intake system for vehicles such as snowmobiles. The air intake system helps prevent airborne contaminants from entering the vehicle engine through the air intake. The intake includes an elongated channel with openings on either end that provides a throughway for contaminants entering the channel. A wall of the channel includes at least one aperture leading to an intake port on an engine cylinder. The intake port is positioned generally parallel to the direction of airflow through the channel.
