61mm Twin Throttle Body 87-96 F150 302/351W

The 61mm Twin Throttle Body for 1987–1996 Ford F150 equipped with 302 or 351W engines is a bolt-on intake manifold upgrade designed for builders and enthusiasts seeking improved throttle response and mid-range horsepower gains. This dual-throttle design replaces the restrictive factory single-throttle assembly, allowing each cylinder bank to draw air independently and reducing manifold vacuum losses.

BBK Performance engineered this 61mm twin-throttle design to match the factory intake manifold opening while maximizing airflow velocity and cylinder charging efficiency. The dual 61mm butterflies work in parallel, eliminating the air-distribution bottleneck inherent to single-throttle systems and improving atomization across all eight cylinders. Precision machining and quality casting ensure durability, making this a reliable foundation for cam upgrades, headers, or fuel system modifications.

This throttle body is ideal for 1987–1996 F150 302/351W owners planning a comprehensive intake refresh or preparing their engine for carbureted-to-EFI conversion. Installation requires matching fuel injector sizing and recalibrating the engine management system to fully utilize the performance benefits of this upgrade.
