I did mine at 90K when I was doing the timing belt.

I did mine around 120K miles. The plugs looked fine and I didn't get any increase in performance, smoothness or fuel economy.

I replaced the plugs in my RX at 160k miles and they looked great! No difference in anything.

The ES has original plugs at 219,000 miles, I'm going in to change the rear valve cover gasket when the weather get's warmer and am debating doing the plugs. I'm a little nervous considering these plugs have been in that aluminum block for over 200k miles.
