BLOX is pleased to offer its updated line of cast, aluminum throttle bodies. These units are cast in aluminum and are direct-fit for the Honda K-series engines. The Tuner Series throttle body looks and feels like an OEM unit but definitely outperforms it. The larger bore sizes help optimize incoming airflow and increase horsepower and torque. BLOX Racing Tuner Series throttle bodies include matching gaskets.
