Thanks so much for the feedback/followup.

So your owner's manual specified a .031" gap?
And the old ones were incorrectly gapped, or worn to .056?

We I did our 4Runner at 30k miles, the wear was visually noticable, but I didn't measure it. And it ran better and has had (slightly) better gas mileage since the change.
