Never heard changing them if nothing is wrong (indications). Save your money...no benifit here.

Its for the old 1 wire o2s they use exhaust heat to reach operating temp wich takes a long time they get dirty and dont work as good ls1 cars have 3 wire o2 sensors one wire heats the o2 sensor so it works faster

over time though even the newer sensors will foul and start drifting. I personally don't change them unless I notice something unusual but they are a maintenance item and you won't always get a light.

You change plugs before a missfire code so why not the o2s... I still havent got around to buying new ones tho
