Spark Plugs, anyone try the new Ruthenium from NGK?

One of the stock iridium plugs at 50k:

The plug tip area looks like crap overall due to age, but the tip does look to be in working order with minimum wear. To be honest, it look fairly clean and not carbon fouled. The plug looks like it could go another 50k miles. However, the gap does look a bit wide so it is probably not firing at it best.

You hijacked yourself, you're the one who started talking about coils in thread # 6, I never said anything about coils before you started talking about it, and YOU are the one who asked me why I replaced the coils, OK!

Uh, that wasn’t me genius. I’m not Nsxnext. Wow.....

WRONG! NSXNEXT asked you why after YOU posted a pic of your Toyota coil fool! Go sober up.

I'd love to try these. Has anyine changed the plugs on their 2015+ V8 yet? If so, how hard is it?

 

[NSXNEXT]

Wow, quarantine is really getting to everyone. We all just need to lighten up.

Congrats on the plug replacement. Gives us another option when they need to be replaced.

I'll give these a shot. i only have 12k on my 2013 oem plugs but they are 8 years old might as well.. chances are theyll look brand new but im 2nd owner so ill have peace of mind. Anyone happen to know th gap for a 3.8 off the top of their head?

PLUG UPDATE:
So I purchased the plugs from Rockauto. Verified with NGK they were not counterfeit and installed yesterday. Pretty easy to do. Drove about 50 miles today, surface street and freeway. Engine is definitely smoother. Pick up seems improved as well. Original plugs had 45k on them, all were clean, but, over 8 years old, so why not? So, I can verify they fit, seem to improve performance a bit, and are worth consideration. Just had to open them up a bit as 44 was needed and they ship at 43 gap, no biggee.

Any long term update on this? Thinking about getting 8 of these plugs for my 2010 4.6.

Did you put them in the r-spec also I've been looking into the BTR ECU/TCU tune for my 2015 sedan 5.0 is it Worth the money for the gain?
