The intake manifold runner control is an engine management component that is found on newer intake manifold designs. It is usually a motorized or vacuum actuated unit attached to the intake manifold, that controls the opening and closing of butterfly valves inside of the intake manifold runners. The unit will open and close the butterfly valves in order to provide maximum manifold pressure and flow at all engine speeds.

While an intake manifold runner is not necessary for engine operation, it does provide the engine with increased performance and efficiency, particularly at low engine speeds. When the intake manifold runner control fails, it can leave the engine without the increased performance, and in some cases even reduce performance.
If intake manifold runner control is stuck, it can cause difficulty starting the engine, engine misfires, decrease in power/acceleration/fuel economy, Check Engine Light comes on. If your car has these symptoms, check the intake manifold runner control and replace it in time. This intake manifold runner control valve fits 07 08 09 10 11 12 13 years.
