They are supposed to be the newest/latest/greatest in plug technology.

Rockauto says... Ruthenium (maximum durability & ignitability).

I am usually a hardcore fan of keeping AC Delco plugs in a GM engine but since NGK and AC Delco are supposed to be one in the same manufacturer now I guess it's kinda 6 of 1 and a half dozen of the other.

Any way like I said... any experience with these???

I guess maybe these are too new for anyone to have tried them???

They are only $8 a pop why not run em and let us know?

Personally I cant imagine you are going to see any significant difference over other properly working fresh plugs.

To be honest I wasn't expecting any increase in performance or anything... I was just curious about longevity.

Rock Auto lists them like this...

Platinum = Lasts 2x longer than copper
Double platinum = Lasts 3x longer than copper
Iridium = Lasts 4x longer than copper
Ruthenium (maximum durability & ignitability)

First I've heard of them. In 80,000 miles I'll be looking for a new set of plugs...

I will be due for new plugs pretty soon... can't remember exactly but I think the ones in there now have maybe 75-80k on them so that is why I'm starting to look.... that's when I saw these listed on RA.

I'm down to give them a try. I need to do mine asap.

As little as I drive mine, *maybe* 4k a year, I used the double platinums. I may pull them when they get to 50k to look at them... in 10 or 12 years.

What do they have for a gap? I see most of the plugs on RA, for the 6.2 at least, are pre-gapped to .040 while some of the NGK’s are gapped to .044. I don’t see a gap on the link from the OP.

At ~100K miles, I'm fine with the lifespan of iridium or even platinum. But if these maintain comparable or better performance than the iridiums throughout that lifespan, then I'd get 'em. Even if they're a couple bucks more per plug, you'd recover from and forget about it long before they're due to be replaced again.
