Throttle Body - 73mm Mustang 4.6L 2V 96-04

The BBK Performance 73mm Throttle Body for Ford Mustang 4.6L 2V (1996–2004) is a direct-fit performance upgrade engineered to improve intake airflow and throttle response on the 4th-generation Mustang platform. This single-blade aluminum throttle body replaces the factory restrictive unit with a larger 73mm bore, enabling better volumetric efficiency and more responsive power delivery throughout the RPM range.

Constructed from aluminum and finished in durable gray powder coat, the BBK Power Plus throttle body maintains the stock flange interface for seamless bolt-on installation without modifications to the intake manifold or fuel injection system. The larger bore diameter reduces restriction at the intake opening, allowing the factory fuel injectors and engine computer to support increased airflow when paired with compatible intake and tuning modifications. Real-world gains depend on supporting modifications—bolt-on intake, headers, and proper ECU tuning optimize the full potential of this upgrade.

This throttle body is purpose-built for naturally aspirated 4.6L 2V owners pursuing incremental power improvements without forced induction. It's commonly paired with cold air intakes, aftermarket manifolds, and dyno tuning to realize the benefits of increased air volume. The gray powder coat finish resists corrosion and blends with engine bay aesthetics on stock or modified Mustangs. Direct fit on 1996–2004 models ensures no adapter plates or fabrication is required.
