Air Intake and Induction » Throttle Bodies


What does a performance or large-bore throttle body do?

The throttle body controls the air flowing into your engine from the air intake system. The throttle body is located between your air intake and your engine manifold, providing fresh air for the engine to execute the combustion process.


Does upgrading the throttle body increase horsepower?

Yes. Aftermarket throttle bodies are designed to improve performance by increasing horsepower and torque. Whether you want to improve acceleration for your ¼-mile times or you simply need that extra power for towing, an aftermarket throttle body can be the perfect addition for you.
