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. Built for street and mild performance applications, this throttle body sits at the heart of any serious intake modification strategy on classic F150s.

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. The compact 6.9 x 6.35 x 11.25 inch footprint integrates seamlessly with stock or upgraded intake manifolds, and the 4.1 lb weight keeps underhood mass minimal. Precision machining and quality casting ensure durability under boost or naturally aspirated tuning scenarios, 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 idle fuel pressure to prevent stumble or surge; pairing with a quality air filter and cold-air intake kit maximizes results. Mechanics and engine builders appreciate the straightforward bolt-on design and proven track record of BBK's dual-throttle platform on small-block Ford applications. Compatible with manual or automatic transmissions, this upgrade suits both street cruisers and weekend warriors seeking responsive, linear power delivery.
