These Zetec throttle bodies have been developed for the Motorsport and modified car markets. The throttle body outlets are shaped to match the Zetec inlet port shape. The transition from throttle bore size to head port shape is gradual enough to ensure minimal disturbance of the airflow, but close enough to the head to maintain maximum airflow as close to the valves as possible. Whilst the inlet track is as straight and direct as possible to maximize airflow and speed into the combustion chamber.
