Yes it can

Are those bosch universal fit o2 sensors a good enough replacemant?? The one from the dealer is way too expensive.

I hear you can order NGK replacements cheap online and they are said to be better than the Bosch ones. And my O2's on my winter car were not hooked up for a bit and never threw a code.

I found a universal o2 sensor made by "Borg Warner" for $50.00 brand new. Are all o2 sensors the same?? Would this one be just as good as the bosch, ngk, or factory one??

those universal bosche o2s have a warranty on them and thats about all i trust bosche too, their wipers and plugs suck ass. (i've had bad experience with all their products, except the o2 sensors)
