Introduction
The throttle body plays a crucial role in your vehicle’s air intake system. It controls how much air enters the engine based on your accelerator input. A malfunctioning throttle body can lead to rough idling, poor acceleration, or even stalling. If you’re wondering how much is a throttle body at AutoZone, this guide breaks down pricing, what affects cost, and what to expect if you’re planning a DIY or professional replacement.
What Is a Throttle Body?
The throttle body is a valve located between the air filter and the intake manifold. It opens and closes depending on how much you press the gas pedal, regulating air flow into the engine.
Modern throttle bodies often include electronic throttle control (ETC), making them more expensive and complex than older mechanical types.
