Downstream on a '08 Kia Rio. I rapped the bottom where the wires come out from the sensor with 'COAX SEAL' to keep out water.  After replacing both sensors, my fuel mileage went back up to about 41 mpg.

Got the oxygen sensor code on my 2005 Hyundai Elantra GT sedan. Bought this part, mechanic installed it. Light was gone, passed inspection this morning!
