This is an easy job so no need to replace all 4 O2 sensors at once.
Let the code tell you which sensor it is pointing to, replace it and rock on!

FWIW, I've replaced one 02 sensor (drivers side pre-cat). I've owned my car since 77K miles (2008) and now have 131K. I would get an occasional O2 code, clear it and it may stay off for many months. Code finally became more frequent about a year ago so I changed the offending O2 sensor...no more codes to date.
