Comments about NTK Oxygen Sensor:

I purchased four O2 sensors and two of the sensors had the plastic packaging opened and the sensors were previously installed. I am not too happy paying full price for previously installed components. I really hate having to work with Advance Auto Parts; I use them as a very last resort.

        Make sure you spray on liquid wrench about 5 minutes before tou attemp to take off. Also use the split socket to remove and replace, I purchased one at Harbour Freight for $5.00 or maybe you can rent one from advance it's usually free.

              After several codes on the bank 1, oxygen sensor 2, I replaced the sensor with this one. No problems or codes afterwards and the car even idles smoother.

                    I had a check engine code that indicated a bad Catalytic converter. I replaced that and check engine light still on. I then replaced oxygen sensors and all is well so far. Two weeks on truck and running with no check engine light.

                          Happy to help you with your question Ace! Oxygen sensors that come stock on vehicles will usually be narrow band. Wide band sensors are used in performance applications.

                          It should be driver side, on the exhaust system, before the catalytic converter.
