My 2000 has 52K miles and runs great. When might I think about wires and plugs?

Good question.
I have 115,000 miles on my Impala 3800... think it'* time to replace the originals?
I wouldn't recommend this, but I usually don't bother to change them unless the car starts to run bad, or a significant change in gas mileage. Then it'* the first thing I change, along with the wires.
Anyone know what the recommended life is? (without having to actually check the manual?)

Irridiums may last close to that, but not in all cases. In your case, your plugs may have degraded so slowly over time, you won't know how much you'll benefit until you change them and say "wow"!
