Between the air cleaner housing and the intake manifold of the engine is the throttle body, which controls how much air flows into a fuel injection engine. Within the throttle body, the throttle determines the rate of air flow by opening so that more air can be allowed to pass as soon as the accelerator pedal is stepped on. As this air flows through a round, tubular section of the housing, information from various sensors is collected and relayed to the control computer of the engine. From these data, an ideal fuel mixture for the inflowing air quantity is then calculated. Compared to an OE-equivalent throttle body, a performance-oriented throttle can give the engine more power, which is exactly what sporty drivers love.

more air = more power

The more air we can pump through, the more power it delivers. Performance-enhancing throttles are built with airflow tubes that are larger in diameter than the stock OEM tubes. Of course, this increases the airflow. Throttle bodies receive an air flow rate based on the amount of cubic feet of air that can flow through in one minute; called "CFM" for short. As more air is pumped into the engine, more fuel can be burned, which creates more power. Since the sensors already mentioned measure the air flow rate, the electronic engine control can also adjust the amount of fuel, i.e. increase it, if the air volume increases. As a result, a denser mixture reaches the pre-combustion chamber, with the maximum air-fuel ratio of 14 parts air and XNUMX part fuel being maintained. This mixing ratio ensures the most complete combustion and the higher density for performance optimization; so for more horsepower under the hood.

It is important to note that if the air-fuel ratio should deviate in either direction, a loss of power occurs, which is why Cold air intake system must be precisely matched to the engine. To make it clearer, pumping more fuel into an engine without increasing the amount of air would not produce more power. Instead, unburned fuel would run into the exhaust system. Conversely, if the amount of air is increased without pumping more fuel, the engine would run in a too “lean” state. In most cases, it would be fatal to install the largest throttle valve available. Because if the engine control or the fuel pump cannot deliver the right amount of fuel, the car slows down and accelerates only slowly.

Most automakers measure the airflow at peak speeds and then choose a throttle body diameter, with which they ensure that 50% throttle accurately generates 50% airflow. This leads to a rather leisurely engine response and performance development. However, the engines are easier to control, which avoids cavalier starts. Since the throttle in an air intake system is designed so that the throttle opens proportionally wider at low speeds, more power is produced with less delay. This steeper response speed of the engine, combined with additional torque, gives you a sharper bite engine, which is particularly noticeable at low speeds.
