The induction system includes improved filtration, and accessibility characteristics. The air induction system can include a plenum chamber member defining the plenum chamber. The air induction system can also include one or more throttle bodies within the plenum chamber to allow the construction of a large plenum chamber. The plenum chamber member is can comprise at least three parts with at least one part being disposed substantially above the spark plugs and being removable. The air induction system can also include an air filter having a water repellent element and an oil-resistant element arranged such that a flow of air entering the combustion chambers passes through both the water repellent and oil-resistant elements.
