Ok, my car had this black plastic cover underneath the front of the car. It mounted to the front chin spoiler and went back to the radiator support. It basically covered up the front of the radiator from underneath. what is it called? Anyone have one or pics? What is its purpose? I removed it when I bought the car because the mounting holes were broke to the spoiler and it would fall and drag on the ground. Also my air dam is mounted further back than the ones I've seen on here. Whats up with that?
