Over the past two years, Bell has conducted extensive prototype and track testing with our top professional NASCAR drivers to improve airflow, ventilation and cooling in high temperature environments. The Infusion uses Bell's Air Chamber technology to create pressurized chambers inside the helmet to help accelerate and route airflow for maximum ventilation. The Infusion is offered in a left side air and right side air version. Airflow is directed to the front of the face.

The Infusion will be used extensively in NASCAR and Sports Car competition in 2007.
