Since the 1980s, Spoon has been enlarging throttle body diameters on our race vehicles — a practice Honda themselves later adopted for their high-performance production engines. We were already there. Our Venturi Big Throttle Body pushes the butterfly diameter to its engineering limit. The inner bore is ground and mirror-polished for minimum intake resistance, and the body geometry is redesigned to exploit the Venturi effect for maximum volumetric efficiency. Increased absolute airflow. Sharper throttle response. These are not approximations — they are the result of relentless trial and error, unbound by convention. Spoon's development philosophy has never been to follow the industry. It has always been to define what the industry follows next.
