Turbocharged 4.6L 3V, 6 PSI, Autolite HT0 plugs.
Never seen a plug do this before. My first impression is obviously piston to spark plug contact but then I noticed how the center section of the plug seems to be pulled down towards the ground electrode. Only thing I can think of is the piston hit the electrode driving it down into the plug and causing the center electrode to mushroom like that. Any suggestions? Can anyone suggest a better plug for the 06 keeping in mind the car is boosted?
