INTAKE AIR SUPPLY CONSTRUCTION FOR ENGINE

An intake air supply construction for an engine includes an intake pipe 6 through which intake air passes, an intake manifold 2 that is connected to the intake pipe 6 so as to induce the intake air into a plurality of intake ports that are aligned in a cylinder head and an intercooler 15 that is incorporated in the intake manifold 2 so as to cool the intake air. The intake manifold 2 has an inlet 21 that is provided to lie closer to one side surface 2a of two side surfaces 2a, 2b that intersect an aligning direction L of the intake ports. The intake pipe 6 is connected to the intake manifold 2 in such a state that an axis center of a downstream end portion 6A thereof is inclined in a direction in which the axis center moves towards the other side surface 2b as the axis center extends towards a downstream side of the flow of the intake air.
