An induction system supplies air to the engine for combustion. The induction system comprising an intake box, an intake silencer, and a set of intake pipes that extend from the intake box to the engine. The intake pipes extend upward and inward toward the engine. A protective chamber is formed by an inside surface of the intake box, an outside surface of the engine and a lower surface of the pipes. A vapor separator is disposed within this protective chamber. The protective chamber can be augmented by an overhanging portion of the cylinder head, a protrusion from the cylinder body or other extensions from the intake box.
