NGK Ruthenium Plugs?

[Dice Roll]

Anybody try these? Suppose to be longer life, seems I see a lot of guys complaining about plug life. I could see their claim for that being true, the lne I doubt is the part about better mpg and response.

If plugs last too long and aren't periodically removed, they can end up welded to the block and become very hard to remove. I remember this was something of a problem on the early 5.4L Triton motor where the stock plugs had a 100K life.

They are the best you can buy for the Ecoboost, most people running tunes are using those. Usually gapped at .028 (not sure that's necessary at stock power) Put some nickel anti seize on when installing and they're less likely to stick over the long haul.

Thanks I was wondering if they did well, sounds like they do.

I wouldn’t leave the factory ones in for 100k and wouldn’t these either. I think it’d be about thirty bucks more than iridium.
