GM Throttle Body Spacer

A GM throttle body spacer refers to the accessory of the air intake system of a General Motors automobile. As the name implies, the throttle body spacer provides space allowance for the throttle. The throttle is the control valve of the air intake system. The throttle is comprised of a narrow nozzle and a butterfly valve. It regulates the flow of air into the combustion chambers in terms of speed and volume. When the throttle is fully opened, the combustion rate is at its maximum level. Hence, when the car is said to be in full throttle, it means that the car is in full speed or full power. On the other hand, the throttle body space aides the throttle in regulating the flow of air that enters the combustion chambers.

Typically, a GM throttle body spacer is a cubical, aluminum metal block that has a cylindrical hole in the center. The wall of the hole has spiral grooves and ridges that modify the airflow. Similar to a gun barrel, the grooves and ridges of the throttle body spacer facilitate the flow of air. The partial vacuum created inside the combustion chambers after exhaust stroke draws in air through the air intake manifold. The air passes through the GM throttle body spacer and then through the throttle itself. The grooves and ridges of the throttle body spacer disturb the airflow, making it highly turbulent.

Consequently, miniature air vortexes are formed. The air vortexes significantly increase the combustion efficiency of fuel. When the miniature vortexes encounter the fuel mist inside the combustion chambers, the fuel mist droplets are further atomized, making the fuel/air mixture more homogenized. Hence, the fuel can be completely burned because the surface area of the fuel mist is drastically increased by the air vortexes.
