HI,

The intake manifold tuning valve is a ‘door’ that changes airflow thorough the intake manifold. Typically, at idle and during part throttle acceleration the valve is closed. When the valve is closed, the intake manifold runners are separated into two areas. During wide-open throttle acceleration, the valve is opened. When the valve is open, the intake manifold effectively becomes one large airflow chamber.

By creating one large chamber, less resistance to airflow is created. This decrease in resistance increases the volume and velocity of air that enters the engine. More air and gasoline entering the engine increases the torque (power) output of the engine.

When it is not working properly, symptoms range from hesitation, surging, poor gas mileage, or loss of power. It may exhibit one or more of these symptoms. Replacing it will resolve your issues.

Directions are attached for replacing it.
