K&N - 87-1124-3 K&N Air Flow Demonstrator;110V

The K&N Airflow Demonstrator is a simple yet effective way to show something unseen - air flowing through a filter! Watch as the restriction from a typical paper air filter is compared to the restriction in a K&N replacement air filter. Use in parts and service departments to educate customers on the benefits of K&N High-Flow Air Filters.
