The throttle body and intake plenum found on your 4.6L SOHC Ford Mustang GT go hand in hand. These two items usually are one of the first mods that Mustang owners do to promote better airflow to the intake manifold. Aftermarket throttle body and plenum are designed to encourage a better incoming air charge; this, in turn, provides your engine with more horsepower and torque.

Throttle Body Vs. Throttle Body Intake Plenum


The throttle body found on the 4.6L SOHC Mustang is the primary metering device for the air entering the engine. It connects to the intake tubing or cold air intake if equipped. When you hit the accelerator pedal, a cable moves to open or close the internal butterfly valve. The throttle body also incorporates the throttle position sensor or TPS. This sensor sends a signal to your PCM, letting it know what range the butterfly valve is.

The intake plenum is the component between the throttle body and the intake manifold on the 4.6L 2V. This plenum, also called an elbow, directs air from the throttle body and sends it through the intake. The intake plenum also houses many integral vacuum ports for different functions of your Mustang’s operation. Your 2V plenum will also be the mounting location for the idle air control valve or IAC valve. This is what controls the idle quality of your engine.
