Opening in front air dam/ bumper--what is it?

[gregross]

My Ex, XLT with the tow package just came in to the dealer. I went to check out (don't have delivery yet). I noticed that there is an opening in the front bumper/air dam on the passenger side of the vehicle, that I had never seen on any pictures before. Does anyone know if there is a piece missing or is this due to the tow package? The dealer didn't know.
Thanks

I noticed that the other day on my LTD, I have the tow package as well so I agree that it must be functional.

I'm pretty sure if you have the two package, you have a larger lower dam. I assume for cooling purposes.

our ex also has that big air dam/channel and we also have tow package

I'll have to look at mine. Maybe this is for air intake for the extra oil cooler that comes with the Tow Package??

The larger opening is for the trailer tow package.

edit: Does anyone have pictures comparing the two bumpers?

I am referring to an opening below the basic air flow opening. It is the lower section of the bumper/air dam on the passenger side.

From what I've read, I believe it's to direct cool air back onto the transaxle to help cool it when towing.

All the vehicles with the trailer tow package has it.

It was stated a while back that ALL Explorers had a trans cooler. So, I suspect this device on the Explorers with the tow package, is an air intake for the oil cooler. Since the oil cooler only comes with the addded tow package.
