BLOX Racing Tuner Series Cast Aluminum 70mm Throttle Body for Honda B/D/H/F Series Engines

BLOX Racing Tuner Series Cast Aluminum 70mm Throttle Body for Honda B/D/H/F Series Engines

The BLOX Racing Tuner Series Throttle Body is a high-performance upgrade designed specifically for Honda B, D, H, and F series engines. Crafted from durable cast aluminum, this 70mm throttle body offers an 8mm larger bore than the OEM 60mm unit, resulting in a 23% larger air intake opening. This increase in airflow translates to dyno-proven gains of 12-15 wheel horsepower on modified engines with port-matched intake manifolds.

Engineered as a direct bolt-on replacement, it includes a matching gasket and maintains compatibility with all factory sensors and the idle air control valve (IACV), which can be used or blocked off for race applications. The throttle body features a dual bolt pattern to fit multiple intake manifolds, making it a versatile and OEM-quality casting that retains a stock appearance while delivering enhanced throttle response and power.
