105,000 mile plugs out of my Escape.

Iridium plugs are pretty **** impressive. Changed the factory plugs in our 1.5L Ecoboost at 98k miles and they looked okay. Had no performance reasons for changing them, just maintenance since NGK says they're good for around 100k. Car didn't run any "better", get better fuel economy, etc with the new plugs.
Spark plugs? hahah, that's funny. I have cockroaches with the same goal.

Wouldn't new ones have been better?
Sorry couldn't resist. Did you notice any difference?
Looks like the gap has gotten a little wider on those old plugs.
No difference at all.Wouldn't new ones have been better?

Yeah. Palmetto bugs. 2 1/2 inches long and they can fly!
Doesn't Ford get their long life plugs from NGK? Or Denso? Maybe either or?
Pretty sure they are almost all NGK. They aren't expensive and at 100k I probably would have just replaced them if I was gonna go through the trouble to pull them out. Especially since the threads are very dirty so the next time you go to pull them out they might be even worse.
Way back with my '95 Integra GS-R, the OEM double platinum plugs were easy to pull even with their 60K mile recommended change. But even at that age I checked the gap and they were fine past 70K miles. I bought some replacements where only the dealer had them gapped to 1.3mm. But a shop said it was fine to re-gap them if care was taken to not damage the platinum.
I've never pulled out plugs on a boxer or a V engine. Scares the heck out of me.
I think those Motorcraft Iridiums are NGK. What is that stuff on plug #2? 
I'm going to assume that the OP regapped before reinstalling.
Im not sure what that is. It was very clean around the plug before I pulled it out.I think those Motorcraft Iridiums are NGK. What is that stuff on plug #2?
I guess I wasn't clear. I replaced the Plugs with new ones of the same type and brand.

Maybe the cockroach crawled in their and got roasted and toasted.I think those Motorcraft Iridiums are NGK. What is that stuff on plug #2?
That gap tho...
Good work!
Is it an easy job on this vintage of Escape? I can't see not doing this at this age/mileage if it's easy to do.
It doesn't look fun at all on our 2019 Pathfinder with the VQ35DD. A lot has to be removed to get at one bank. We're only at like 62K miles, so it's got some time. LOL.

My Tacoma 4.0L had the originals till 60K. 30K intervals since their copper. Gas mileage stayed the same afterwards.
