Upstream or Downstream O2 Sensor? interchangable?
my downstream o2 sensor(on cat) is shot, so i just bought a new denso one for my car on ebay, but it doesnt specify wether its the upper or the lower one, i mean, are these 2 sensors interchangable? or are they 2 completely different?

ok cool, so just in case, would an o2 sensor made for the header fit right into where the cat one is supposed to be?, i mean like wiring & fitment wise?
thanks
thanks

It should. I know on the Integra, the secondary sensor has a rubber grommet to seal the hole where it enters the car, and the wiring might be a slightly different length. I'm not entirely certain, but I assume it's a similar situation with the Civic. Either way, it shouldn't be a big issue.

ok, what about the plastic connector harness? are they still both the same on upper and lower?
