ABSTRACT:
An intake manifold for an internal combustion engine having a plurality of cylinders is composed of a primary intake manifold assembly including a plurality of primary branch pipes extending from a two-barrel carburetor to the cylinders, respectively, and a secondary intake manifold assembly including a plurality of secondary branch pipes extending from the two-barrel carburetor to the cylinders, respectively. The primary and secondary branch pipes are joined together immediately upstream of intake ports opening into the combustion chambers. The primary and secondary branch pipes are dimensioned to meet the relationship of (n-1)S.sub.1 .ltoreq.S.sub.2 where S.sub.1 is the cross-sectional area of each of said primary branch pipes, S.sub.2 is the cross-sectional area of each of said secondary branch pipes, and n is the number of said cylinders.
