It forces more air through the radiator. If the undercover is not working, a large amount of air will go UNDER the radiator instead of through it. There is a 5-8c drop in temperature by having a fully functional undercover. It also improves the aerodynamics of the front end, which will lead to slightly better highway gas mileage and less frontal lift.
