An engine intake manifold includes a casing having a plurality of air intake passages, and a plurality of valve plates, wherein each valve plate is disposed in one of the air intake passages to control airflow through the air intake passage. The valve plates are connected to a common valve shaft for rotation between an open position and a closed position. The engine intake manifold may further include an actuator that is mounted to the casing or to the valve shaft via a snap connection, and is rotationally connected to the valve shaft to allow the actuator to rotate the valve shaft.
