What is this part?
 

This is located in the top passenger rear fender. I have a pic but I cannot upload right now for some reason. It has two lines, one going to the back of my air intake and the other goes to some small line leading to the other side of the engine compartment.

I am removing it to get to the targa bar and rear window trim.
Could it be an oil overflow container? I just want to know how to label this thing.

Thanks for any help.

There's no fastener on the end of the hose that attaches to the thermo valve behind the throttle body, mine slipped off and gave me a flat spot in the throttle ~2900 rpm. Just a heads up if you are working around that hose.

AFJuvat,
Thanks! That must be it.

Jojo - thanks for the heads up. My engine is out of the car right now and it looks like one of the hoses to the Ambient Air Valve is cracked - the far right one in the pic from your link. Now I know where to get it.
