In an internal combustion engine, one of the most important systems is the air intake system. You actually need more air than you do fuel for proper combustion, and any increase in your air supply will allow you to increase the amount of fuel you burn. If you have a Ford vehicle, a great way to increase your air supply is to install a larger Ford Racing throttle body. While most people think of the accelerator pedal as the gas pedal, it is actually an air pedal. The throttle moves a butterfly valve in the throttle body, which lets in air, and the amount of airflow determines the amount of fuel flow. With a Ford Racing throttle body, you can increase your air supply by as much as ten percent. It may not sound like a lot, but it will really show in the throttle response. A Ford Racing throttle body is designed to work with your existing OEM intake manifold. Because it is made by Ford, you can be certain that it will fit right and work right on your Ford vehicle. The Ford Racing throttle body contains a an idle bypass valve and a throttle position sensor, so you are guaranteed great performance and a smooth and hassle free installation.
