part question

This is not really a technical question but I hope someone may know the answer. I have an Alero and on the front of the car there is a plastic thing that is attatched to the bumper that runs the width of the car. It is really damaged and I would like to know the name of it and where I can find one. Thank you for your time.

Is it located on the bottom of the bumper, like a spoiler or chin? Or is it pretty much hidden from view, and plain plastic? The first one is called exactly those names, the second option is called a front air dam. The spoiler/chin would be more expensive, and both can be found at dealers. Or Oldsmobile parts wholesalers.
