I have only 2 on my car, rears are plugged, does all US c43 come with 4 o2 sensors?
Bosch claims 100.000 miles on them, mine broke at 55000km, seems like these sensors doesn't hold their quality as they should.

I also only have two on my Euro version. I guess the NA version had 4 (California smog norms perhaps?)
