I'd like to gently disagree with Donovan. I think the low pressure area happens behind the air dam, pulling the hot air through the radiator and down under the car as it sails along. I think that's the point of a splitter, to create a low pressure area under the car, increasing down force on the front end.
I have captured two of the SS urethane air dams over the years, both in 'meh' condition...some rework will be required...I'd like to confirm that the black plastic part is still used when one of SS dams is there, so I know what to install when the cars go back on the road.
