Hard to say. Depends on what sort of conditions they've seen over their lifespan.

At 150K miles, i would replace them with some motorcraft units for peace of mind.

If you cannot find a motorcraft, the ONLY aftermarket oxygen sensor I have had any luck with is Bosch...

you'll pay more for stuff like common replacement parts there, go to rockauto and find some motorcraft or bosch.JMO
