ABSTRACT:
An intake module includes a surge tank, inflow ports formed from resin integrally with the tank and aligned in one direction of the tank, an intake air leading portion formed at one end portion of the tank in a certain direction and leading intake air into the tank, and a return pipe portion. Each of the ports is connected to a corresponding intake manifold. The certain direction is generally perpendicular to the one direction, and to a flow direction of air flowing into the ports. The return pipe portion is disposed at the other end portion of the tank in the certain direction. The ports are located between the leading portion and the return pipe portion. The return pipe portion communicates between the tank and an exhaust pipe portion, and projects into an inside of the tank. Exhaust air is returned into the tank through the return pipe portion.
