The Intake Manifold Runner Control system is an emission control device intended to control the incoming air into the engine through a dual plane intake manifold. The runner control system consists of an intake manifold with two running planes, a long running chamber and a short running chamber. As the throttle plate opens and closes under normal driving conditions the pressure in the intake system will vary widely causing a variance in available oxygen in the combustion chamber. The ECM will provide the engine with the optimum oxygen amount using a control valve operating the air control plate. Product Features:Product constructed to meet all design and operating characteristics as intended by the vehicle manufacturer.
