An intake manifold for an internal combustion engine includes a rigid intake pipe having a flow-through passage, and an adjustment structure for adjusting the size of the flow-through passage. The adjustment structure is a check valve which opens only in direction of the internal combustion engine and includes a valve body and a valve seat which are movable relative to each other and are selectively interengageable for the closing of the flow-through passage. The check valve prevents a backflow of gases from the internal combustion engine into the intake manifold thereby increasing the engine's power output especially at low engine speeds.
