ABSTRACT:
An intake manifold for a multicylinder internal combustion engine has a riser connectable to a carburetor and branch pipes connecting the riser and each suction port of respective cylinders of the engine, and is characterized by being provided with orifice means located at a position in each said branch pipe for defining the cross sectional area of the position to a preselected magnitude thereby rendering pressure in each said branch pipe and each said intake ports of the cylinder equal. The orifice means can be constituted by a plate-shaped gasket having orifices to be located in the positions in each said branch pipes.
