Long Term Spark Plug Thoughts

[ChrisMk77]

thanks guys
what are the advantages of ngk ruthenium spark plugs compared to origins? better performance? cooling?

Only real difference I have noticed is better E85 coldstart, but they where developed as improvement in both durability and ignitability over OE Iridium.

They are stock heat range but have a special tip design....probably zero advantage over stock but I run them anyway!

It’s cool to say “I run ruths” and have other people not know what you’re talking about.

Agreed. Good when you are hard park at "da meats" and tell your stance friends about it.

I've been running Rutheniums for a few years now. Back when I had a stage 2 2015 they were the only plugs the car seemed to like. Now I run them in my 2019 because they are easy to find and I have no reason to change.

I switched to Ruth's about 2 months ago, picked up about 1.4 mpg on average. Over the course of monitoring 4 fill-ups, as compared to what I got with OEM plugs.

Are y'all gapping your ruths, or running them as they come? @EpicTech @Supermoto

Gapped at .024 sir

Generally the gaps they came with were spot on for me, but I just check them with my 0.028 feeler guage to verify.

Just got a fresh set and all four were at .030 out of the box. I brought them down to .024-.025.

Some good info on plugs, gap, projected/non-projected:

For the hell of it, I pulled my plugs at 2,000 miles and was not expecting them to be straight-up black at the top of the threads. Is that normal?

Those are 2 stage colder race plugs right?

Looks to me - you’re not racing the car enough and getting the combustion temps up.

Yet another reason for the 2 dollar spark plug club will say “Ruths”
