In fuel injected engines, the throttle body is the part of the air intake system that controls the amount of air flowing into the engine, in response to driver accelerator pedal input in the main. The throttle body is usually located between the air filter box and the intake manifold, and it is usually attached to, or near, the mass airflow sensor. So, the simplest but essential way to increase air intake into the engine is increasing the diameter of the throttle body. By doing so, more air volume and higher amount of fuel are introduced, then, higher power will be available at your feet. This Throttle Body would be a must for a tuned or upgraded vehicle with higher than stock horsepower.
