NGK TR55Ix Plugs

To the more seasoned eyes, how does the burn look on this plug? Also, the gap looks a bit large, but I haven't measured it yet.

Read a few post going back to 05 on Plugs...what is the current consensus for the Vortec 5700? Seems there is a good amount of confusion for which plugs to use..AC VS NGK.

TIA,

Buhler? Buhler?...which is the preferred plug for the Vortec 5700? And what is the Gap?

Ac Delco 41-993 is what I use. Gap is spec put of the box.

Ac Delco 41-993 is what I use. Gap should be spec out of the box.

Fixed it for you.

It's too easy not to just check them real quick before they go in. I've had to make adjustments.
