Spark Plug read

[Handlebar Moustache]

I was poking around under the hood and decided to pull a couple of plugs as a random health check. I’m on 93 octane; stock internals; about 17-18 lbs of boost; Lund tune. Any opinions?

looks ok, but time for new plugs.

you wanna look at the "white" and make sure you dont see any "silver flakes" which I dont see

a super white center means running to lean ....yours looks fine,.

What do you guys think of these plugs out of my 2016 AMG E63?
After seeing them I traded the car.

Wow at the top left! Oil control problem in that cylinder?

I think it was probably cracked ring or rings.... The replacement cost for engine and labor was close to $75,000 Canadian if not covered by warranty. I know this because I checked with the dealer before I tuned it. ‍

Do you think the motor was pooched or a tuning issue?

It ran strong but something made me very nervous.

Good choice on trading it in. Looks like you would of been in for an expensive repair
