That is the Radiator Air Deflector (Parts Group 1.272, Part # 147 9472). It attaches via 4 bolts to the bottom of the radiator support and lips above the front lower center bumper end bar. It helps funnel air through the radiator by sealing from below and serves as a rock & debris shield. It should definitely be installed on any your car if it has been removed.
Here is a picture of mine:
I'll have to check our car, but I don't recall having that.
It was there from the factory.
... but have often seen them removed and not reinstalled.
Hey Jason, do you have one and if so, how much?
I am out right now. Maybe Russ or one of the others reading this has one. If not, I can add you to my Wait List.
Can you please bung me the wait list.
I'll check with Russ as well, but if you haven't got one, I doubt anyone would.
Kev, I have one for you. email me at; firstname.lastname@example.org
If its not there you should get it. In your climate it might help cooling the engine as per Jasons: "It helps funnel air through the radiator by sealing from below". My guess he can get you a good one.
