Do I need to replace these NGKs?

[Jaynet]

Hey everyone!

On my new to me 2019 DT, I pulled a couple of plugs to inspect them and to try and determine whether or not they need doing. My first hemi and they don't look terrible to me, but I'm hoping some of you with experience can guide me in the right direction. The truck has 130k miles on it. Are these original, or have they been changed out once already?

Cheers!

They look pretty good to me, they could have been replaced at 100k as per service schedule, you could run with them till you start getting misfire codes.

They look good to me.

The tip has almost no discolouration.

But you cant see whats going in inside the insulation. If it were me id keep running em. And run some liqui-Moly injector cleaner.
