oxigen sensor (lambda)
 

hi all, i'm having a little problem. i live in Brazil, and my car had a problem with an oxigen sensor. the part costs here about US$1700.00 (R$ 3000.00). i'm pretty shure that this part does not cost much more than US$ 200.00 there, but i can be wrong.
The part number is vol8631643. it would be great if someone could tell me where to buy this in the US (or maybe in europe too, preference to Germany) and ship to Brazil.
if it can help, my car is an 98/99 2.9 150KW(204HP) S80.
