What is the name of this part?

Hell
Connected below the front bumper. Made of rubber. I hit the sidewalk and the part fell off. Now the threaded holes appear to be too large and do not hold the screws

I have no idea what the name of this part is or its serial number.
Thanks

It's an air dam, I haven't seen any Yaris around here with them stock, only the Prius C has one. What model do you have exactly?
