Abstract
A multiple-runner intake manifold is constructed of upper and lower parts that fit together at a joint. The upper manifold is molded thermoplastic, and the lower part is molded phenolic. The lower part contains an integral fuel rail. The lower part contains a portion of each runner. Those portions are formed as separate through-passages during molding of the lower part in the cavity of a multi-part mold. The fuel passages are molded as through-holes some ends of which are subsequently plugged by closures and other ends of which receive fittings.
