NGK Ruthenium plugs

[Remoat]

Anyone using the NGK Ruthenium spark plugs? I'm shopping around and trying to decide. I 've search for these NGK's in the forums but didnt find anything. Wondering if they worth paying extra...

Not running them in the 6.2 but I ran them on my previous car, Mazda DISI motor, it was DI and high boost which is really hard on plugs. Would normally replace iridium's at 15k intervals.

Not sure its worth the extra cost over the regular NGK platinums/laser iridium's in this case considering they are good for 100k.

100k? That would be nice! I generally only get about 30k out of OEM plugs before I start to get misfires/rough idling. The plugs have always had high speed glazing signs on them... Must be due to my rare deformity where my foot has the same density as lead.

The ruthenium plugs fire quicker and longer supposedly so they are a superior plug to iridium. I just ordered my second set for the 18 rap. Also if you wait for Christmas sales or whatever you can usually get them from advance auto shipped for around 50-60 bucks for a set. If you have rewards dollars through advance that helps too. I believe they come gapped at .31 so if you want a colder plug just get out your gap tool and regap them to whatever you want.

WTF is Ruthenium? lol

I have them in my 19 with a 91prx tune over 30000 mi and working great.Ruthenium hx LTR7BHX #95605

Just looked up the NGK Ruth’s on their site, and they show a different part number and gap. Is the part number you posted for your 19 due to the tune you have?

Ruthenium is an element, atomic number 44, atomic weight 101. It is the first of the precious metals, and one of the minor platinum group metals that occur with platinum in ores. In every day life you are most likely to have encountered Ruthenium as a thin plating on jewelry. Ruthenium plating is used in jewelry due to its high resistance to corrosion. It has a darkish grey, pewter-like shine. As with most of the platinum group metals, Ruthenium has application as a catalyst and alloying agent. One exotic example of the use of Ruthenium: single-crystal superalloys used in high performance turbine blades when mere cost is of no concern.

It seems to me to be too exotic a material for spark plugs except maybe in race engines and other very high performance applications. This reminds me of exotic fishing lures that catch more fishermen than fish, and the use of titanium in the exhaust systems of street vehicles. Overkill for suckers? Maybe so.

I will be changing my spark plugs in the summer with the Ruthenium LTR6BHX-PSPE from Iridium LTR6IX I have now..
I always believe in getting the best whether it's over kill or not.
It's like running Hi-Test, you don't need to but the extra HP and fuel economy, keeping things in the combustion chamber, Cats and O2 sensors clean pays for it's self in the long run.
So if I don't need to change them as often and I get better performance how ever slight it might be, I'm good with it.

Also since I'm Supercharged the recommended gap is .28
And I've seen Tuners say .28 to .30 on a Tuned 6.2L will minimize misfire and and make it run smoother.

I just learned something about our dual spark plugs.
I always wondered why the spark plugs look different when pulling the old ones out. It's good reading.

My exact thought! At first I thought someone meant Iridium and got a word mixed up.

Thanks for posting that and saving me from having to look around on Google. This was definitely a new one on me. I thought I remembered a lot of my chemistry from school, obviously not!
