oxygen sensors?

[ground_zero298]

I pulled my o2 sensors today all of them are the same ending in A2A. I got a bunch of ntk's oem from romeo ford that end in A1A. Are they interchangable?

Anyone? maybe i'll put them in just to see what happens

I don't really know the difference but I was always under the impression that there were only a few different types of O2's... Narrow, Wide, Preheated, Non...
