Here's mine at 91,000 miles. After the photo session, I cleaned them up with a wire brush, re-gapped them, and put them back in.
Mine are over $12 a piece and I have to buy six of them plus new wires; I'm pushing them farther for now.
Here are mine at 42k miles:
I replaced them. These are the kind where it is not recommended to do any regapping.

Yeah, but how long are the copper plugs good for? 5-10k miles? I don't have the time to replace them so frequently. Besides, the platinum electrode ones are the OEM plugs for my car. They still have a copper core though.

Forget those boutique iridium/platinum/unobtanium spark plugs and throw in a fresh set of standard NGK copper cores.
Your engine will not know the difference and you will be lots of $$ ahead.
LOL! 2 things I can see that would require "boutique" spark plugs: a) long wearing characteristics(long service life), (b)time involved in re-and-re spark plugs in many modern engines (esp. transverse mounted Vee6/8.
Copper??!! Why? It's not that cheep anyways and besides: who wants to have time replaced every 1.5 yrs time?
BTW: the frequency of replacing coppers will offset the use of boutique plugs in terms of $$$ saved.
And here are mine after 75029 miles in the '02 Accord V6. They were replaced with Denso Iridium.
buster-nice plugs for an oil burner
Benjamming-
Does your neighbourhood gas pumps carry MMT-laden gas? Curious as I can see a tinge of pink on the ceramic nose...
(*no, I absolutely refuse to pay my dues to evil Ethyl corp for the MMT additives in Canada, period*)

Q.
Buster, it looks like the platinum disc on the ground side were missing in your first two pictures. I wonder where they went. Did they fall into the cylinder or did they burn up? I've heard of this happening on some AC Delco platinum plugs. So far on my Ford that has the platinum discs on the ground side they were still there when I changed them at 55,000 miles. Ford suggests 60,000 mile plug changes on my car.

OOPS! Sorry Buster, I made a mistake. I thought the pics after your post were part of your post. They had the ground discs on them. My bad
! Your plugs looked fine. I think that most platinum plugs can fire ok for 100,000 miles. The real problem with leaving the plugs in for 100,000 miles is will you be able to remove them.

Holy gap-ola!
I don't think MMT is allowed in the gasoline in the USA. It's apparently ok in Canada.
Quest,
The cheapest gas availabe was used almost entirely during the life of those spark plugs. It's very doubtful MMT was in the tank - no trips to Canada.

Hey benjamming, which cylinder did the plug with the rusty threads come out of?
