Definition: A front spoiler mounted beneath the bumper and shaped to reduce the airflow under the car. Air dams can increase the airflow to radiators, reduce aerodynamic drag, and/or reduce lift.

The underside of your van isn't very smooth. Less air under there is better.

At first glance, I would say leave the design alone or make it a little bigger..
