1. An engine for a vehicle, the engine comprising:
an engine body assembly including a cylinder head and a cylinder head cover, the cylinder head defining one or more bosses;
an air intake system including an air plenum, the air plenum positioned above the engine body assembly;
an air plenum support bracket having an upper arm coupled to the air plenum and a lower arm coupled to the one or more bosses defined by the cylinder head, thereby bypassing the cylinder head cover; and
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.
