Throttle Body - Performance

The throttle body is part of your air intake system. It uses a butterfly valve to control the amount of air flowing into the engine based on the position of the accelerator pedal. An upgraded throttle body can increase airflow into the intake manifold, resulting in more power and improved throttle response. If you have already upgraded your engine with a cold air intake, headers, cat-back exhaust, turbos, superchargers, or other upgrades that help your engine breathe better, a performance throttle body is a must have.
