What Is a Throttle Body and Why Does It Matter?
Throttle Body Definition
The throttle body is a component of the air intake system that controls how much air enters your engine. It’s typically a round metal assembly with a butterfly valve that opens and closes based on your accelerator pedal.
Why Keep It Clean?
A dirty throttle body can cause:
- Poor acceleration
- Rough idling
- Reduced fuel efficiency
- Engine stalling or hesitation
Cleaning it periodically ensures optimal airflow and helps your engine run smoothly.
