BLOX Racing Tuner Series throttle bodies are alternatives to its line of billet throttle bodies. These units are cast in aluminum and are direct-fit for the Honda B/D/H and F-series engines. The Tuner Series throttle body looks and feels like an OEM unit but definitely out performs it. The larger bore sizes help to optimize incoming airflow and increases horsepower and torque.
