ABSTRACT:
The intake manifold assembly comprises three blocks each molded from a plastic material by injection molding, the three blocks consisting of a first block defining a half of the surge tank, a second block defining a half of the individual intake pipes and a third block defining a remaining half of the surge tank and a remaining half of the individual intake pipes. Thereby, the intake manifold assembly may be provided with various features for defining a pair of intake pipe sections arranged in a mutually parallel relationship while being made to be suitable for an injection molding process. Because the surge tank are defined by the first and third blocks while the individual intake pipes are defined by the second and third blocks, the intake manifold assembly essentially consisting of three blocks can internally define essential features required for a dual port intake device without requiring additional component members.
