I'm soliciting input on the condition of this spark plug. It came out of my perfectly functioning 60K miles 05 EX. I just pulled it out to take a look at it.

It seems OK to me, but Autozone has 'em for $9.99 each and they're in stock. No big deal to change 'em, but I'll save the $40 if there's no reason to change 'em.

Save yourself some money and time. Put them back in and run 'em until 120k.

I had mine out for a check at about 40K miles, and opted to put 'em back in for a while more. Yours look to be a tad browner than mine were, but still look fine. Given they're rated to 100K, you're probably right about the point where fresh ones would be worthwhile in terms of efficiency (ie. where you save more than the cost of the plugs in fuel).

You're right, it's a tough decision.

Check the gap

and put them back.

Look fine, clean up the threads through them back in. Iridium plugs should last well past 100k, I typically pull plugs at 80-90K just so I know they come out not that are typically worn.

Make sure to use anti-seize on the threads.

At 60k those plugs look about as good as it gets.

I pulled mine at 86K because of a percieved lack of power. They all had a
rusty look to them and the center electrode looked a little degraded.
Replaced them with Autolite Iridium XP5224 @ $6.71 ea. Bucks well spent.
All the original power came back.

PS. I dont think there is any messing with the gaps on iridium plugs.
