Spark Plugs R&R

[Ltngstrucktwice]

Swapped my plugs yesterday at 65k—lots of negative responses on the FB
What do you guys think of the condition an$ what’s the white build up under the ground electrode.
2025 3.0TT SO 65k
Ran some liqui moly DI JECTRON a few times and use Top Tier pumps at least 80% of the time.
Took about 2hrs total working time going casual.

They look like they are burning okay at the electrodes but the burn marks at the porcelain to metal case look like crap. Those dark orange marks on the porcelain are caused by the spark energy not making it all the way to the tip of the electrode. When this occurs it can make the spark plug appear to be running in a richer condition than what is actually occuring. It can also cause hard starting and misfires. Good on you for getting dirty and changing them out.
