Abstract: An air intake system for a snowmobile which comprises an internal combustion engine having an induction system. A body is provided which cooperates in defining an engine compartment wherein the engine and induction system are contained. This body has an opening for inducting air from the atmosphere and is in communication with a passageway which defines an air flow path from the opening to the induction system so that air flows from the opening to the induction system without accumulating in the engine compartment. A filter element is positioned between the opening and the induction system across the air flow path such that the air flows in a generally upward direction through the filter element. The filter element not only prevents snow and ice from being sucked into the induction system but also prevents these elements from clogging the filter, while still allowing for adequate air flow to the induction system.
