You are wrong about the OEM sensors that come with the 99 dodge ram 1500 5.9 magnums, they were BOSCH, I have bought NTK twice and screwed up my fuel trims both times, so will not be buying japanese garbage again

 

Terribly sorry, but, what you are claiming goes against everything that has been known here for more than a decade. I can't count the number of folks that have bought the bosch sensors, because they were cheap, and their engines did not run properly. Replace 'em with the NTKs, or Densos, and the problems went away. You aren't going to convince anyone here.
