Abstract: An engine includes an engine body assembly and an air intake system including an air plenum. The air plenum is positioned above the engine body assembly. The engine includes an air plenum support bracket having an upper arm coupled to the air plenum and a lower arm coupled to the engine body assembly. The engine also includes a vibration isolator coupled to the air plenum support bracket and interposed between the air plenum and the engine body assembly, thereby inhibiting engine vibrations from transferring to the air plenum.

Abstract: A snowmobile includes a forward frame assembly defining an engine bay. An engine is positioned within the engine bay. The engine has a plurality of intake ports positioned on an aft side of the engine and a plurality of exhaust ports positioned on a forward side of the engine. An air intake system has at least one air inlet and a plurality of air outlets. The air intake system is coupled to the aft side of the engine such that each of the air outlets is configured to provide air to one of the intake ports. An exhaust system has a plurality of exhaust inlets and at least one exhaust outlet. The exhaust system is coupled to the forward side of the engine such that each of the exhaust inlets is configured to receive exhaust from one of the exhaust ports.
