An intake system for a V-type multi-cylinder internal combustion engine includes an elongated collector housing disposed between two rows of cylinders in such a way as to longitudinally extend across the rows of cylinders at substantially the center thereof and at right angles. The collector housing have at the opposite ends spaced along the rows of the cylinders a plurality of openings in two rows. Two groups of intake pipes for the above described two rows of the cylinders are respectively connected to the opposite lateral ends of the collector housing in such a way as to communicate the openings. The intake pipes extend curvedly toward the rows of the cylinders and away from the collector housing and further extend curvedly toward the intake ports and in such a way as to have adjacent the intake ports, circumferential walls which extend across the axes of the intake ports and thereafter extend nearly coaxially with the intake ports.
