O2 sensors

Hey guys,
I am putting a remanufactured engine and transmission in my 2000 SE TJ; should I replace my O2 sensors even though I did not have any fault messages? If so, which brand is best?

If its not broke dont fix it. Also try to change as little as possible until you need to.


Always use OEM sensors. Others fail out of the box.
