I was driving when I turned a corner and hit a low pile of snow someone had made on the road. Didn't feel to bad but when I got home I heard dragging. When I looked I saw what looks like a plastic guard of some sort handing just below my enigine. The front part is off but the back part is still at ached to my car. Is it a splash gaurd or something else and if so what is it and how much is it going to be to replace it?
