Abstract
An intake manifold for an engine includes first and second runners that each extend from a plenum to a mounting face of the intake manifold. The mounting face mates with a corresponding face of a cylinder head. The intake manifold defines a passage directly fluidly coupling the first runner to the second runner to reduce engine noise. The passage is spaced apart from the plenum and the mounting face. A method of controlling engine noise is also provided.
