I understand the burnt one

But the other 2 make me worried

Were they installed that way ? How does the electrode get bent away from the plug after its installed ?

I'm guessing mine will lok like that as well. Gonna pull the drivers side today and check em out.

If i had to guess the closed one probably happened on install and the open one???

Detonation does crazy things to spark plugs - just think : an extremely high pressure blast wave encountering an electrode only designed to handle normal cylinder pressures...................

Agree, detonation bends electrodes.

Had not had any detonation to my knowledge. We will see this weekend I have not fired it since the swap.

Hey, you know a guy that lives in Houma with a white L??

[Silver_2000]

No on the inside, under the electrodes

He asked because detonation breaks the insulator

Yeah had one w/ bad insulator I think we have it dialed in long story but things are good
