Abstract
A composite intake manifold includes a first outer member, an inner member fitted within the first outer member, and a second outer member fixed to the first outer member. An intake port of the manifold includes a curved portion. The curved portion is defined by the inner member and at least one of the first outer member and the second outer member. The curved portion of the intake port is divided at a seam parallel to an axis of the curved portion of the intake port so that the respective members can be molded without using a molding core.
