"5"??? O2 Sensors??????????
Picked up a set of Bosch Platinum +4s yesterday. Asked how much an 02 sensor was - their computer shows 5?
Changing an O2 sensor with the plugs is a pretty good idea - it certainly doesn't need all 5 of them as a tune does it?
Which one do I get for a tuneup?
Thanks

Ya I'm just messing with ya... lol Really you only have two O2 sensors before & after the cat. most people just replace the 1 before the cat, but you could replace both its up to you! X2 on OEM

If there's NO CEL/codes for O2 sensor(s), I wouldn't change a single one, as they should be pretty much spot on and performing well (again, no codes). OBD-II has some pretty tight parameters.
