O2 sensors ?

OK Is there a difference between the HEGO sensors ? manuel vs AOD 1989.

Manuel Part # Ford NGK E71F-9F472-AA

AOD part # Ford NTK E93F-9F472-AA


I am wondering because I have a AOD and the o2s from the manuel are in there right now should I switch them out does it make a difference?

The NGK are much bigger and look different than the NTK. They all have 2 white and 1 black wire. 3 wires total on each. The connectors are the same . Can anyone clue me in as to what the difference is. Thanks.

nobody got nothing to say about o2 sensors.

I could have more problems coming up I need to learn these things. I have heard that O2 codes can be misleading. What are the best O2 sensors and why? what are those wide band o2 sensors about are those somthing you just want to use with a EEC tuner and mods?.
