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.
