O2 sensors are not a part that you cange every day. Or every year. So it is nothing that people would have "favorites". On my 1996 Sable I had change one and on my Hyundai Sonata another - both times I had used Bosch because... no reason. I just wanted something to last so I went by the precieved "fame" of the brand.
If I have to replace the ones in Explorer I woldn't go with Motorcraft. Not after the original crappy spark plugs broke off in my engine when I did try to remove them and cost me 600$ to fix.
i just replaced all mine and went w/Bosch from rockauto. i can not say they are my "favorite" because this was my first go around w/o2's but i am pleased w/them and have nothing bad to say. if i wouldnt have been strapped on cash w/getting new cats, muffler and accessories i would have probably went w/motorcraft to be honest(my old ones went 200k miles w/no problems).
