In the engine intake manifold equipped with a branch pipe, a partition wall is provided inside the intake pipe to partition the intake pipe into two pipes in the direction in which intake air flows, and the partition wall is formed of a shape memory metal. , when the intake air temperature is low, one of the two pipes is closed, and when the intake air temperature is high, all the two pipes are opened, and the suction port is communicated with the branch pipe via the two pipes. An engine intake manifold characterized by:
