Looking to make more power with your 3L V6 engine?
This high flow throttle body has an internal butterfly that is physically larger (see pics) and flows more air than the factory/stock throttle body on your 3 liter V6 engine.  It offers a nice improvement in airflow and best of all it's a direct bolt-in replacement!  
 
 This new larger Holley throttle body comes with an AIS (Air Idle Speed) motor, and brand new gasket as well to make installation a breeze.  Note that you will transfer your TPS (throttle position sensor) to the new larger TB.
