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?

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.
