Ford 75mm Throttle Body - 4.6L F-Series/Expedit.

The Ford 75mm Throttle Body for 4.6L F-Series and Expedition is a direct bolt-on upgrade designed for drivers seeking improved engine responsiveness and airflow efficiency. This BBK PERFORMANCE component replaces the factory throttle body, making it suitable for stock builds and mild modifications. Performance enthusiasts will appreciate the immediate throttle response this upgrade provides.

The precision-machined aluminum body features smooth internal passages that minimize turbulence, promoting laminar airflow for consistent fuel atomization and combustion efficiency. The larger bore diameter enhances airflow, allowing the engine to breathe more freely at various RPM ranges. This design can lead to improvements in low-end torque and mid-range acceleration.

F-Series truck owners, particularly those operating 2004–2008 models, can benefit from this upgrade when paired with cold air intake systems, exhaust modifications, or bolt-on fuel system enhancements. This throttle body is an excellent choice for those looking to maximize their truck's potential while maintaining compatibility with existing systems.
