The Audi S4 Throttle Body controls the proper flow of air in the engine, and each light tap of the pedal results in swift forward movement. Famous for its stability and easy response, this tight gateway airflow opening is located between the air filter and intake manifold, and it opens and closes in milliseconds to allow the Powertrain Control Module to inject the ideal amount of fuel to burn efficiently and produce substantial power. It fits not only early cable-driven S4 sedans, which operated on both Throttle Body injection and later multi-port injected models, which operated on separate injectors, and it directly drops into the highly recent drive-by-wire models, where stability and traction systems adjust the torque in real time to allow the departure of safer corner exits. Internal friction coating is kept to a minimum, and machining is kept to a minimum to allow the unit to resist sticking, and throttle position and idle air sensors allow the unit to maintain revs constant during cold starts or in stop-and-go traffic. Throughout the generations, Audi retained casting dimensions consistent to make swaps an easy task, and the fact that it uses the same blueprint means that an Audi owner can be sure that it can be fitted easily and sealed at a factory level. The owners like the fact that when a fresh Throttle Body is installed, it is usually like factory idle and sharper acceleration that does not require a lot of retuning, something that will enhance efficiency and maintain emissions in check. Since all Audi performance algorithms are tuned to this element, a healthy Throttle Body can sustain the efficacy of the fuels and the emissions, which confirms efficiency and safety throughout the legendary S4. The combination of intelligent electronic control, rough construction and drop-in compatible features indicates why the part continues to be one of the shining stars in Audi performance portfolio.
