BBK's 2005-2010 Mustang GT throttle bodies are designed to increase airflow and improve horsepower from between 15-20 RWHP & an incredible 20-25 RWTQ depending on vehicle and application.
All throttle bodies are direct replacements and include detailed installation instructions.
Note: 05+ Ford vehicles have a re-useable O-ring in the intake manifold that eliminates the need for an additional gasket.
