My spark plug ceramic sections are burning after only about 6-7k :-/
Surely this is not normal, is it???
IIRC your car was running a bit lean until we tweaked it? Might be worth double checking that the vapour pressure is still OK and the O2 sensor output stays solid "rich" under full throttle?
No issues here with the quad electrodes.

Pressure is 1, so thats still fine, i have raised its cut in temp as it was coming in too early causing very rough idle with an occasional mis-fire.
I had the same issue. I found that the temperature is not such an issue, it's switching over to gas too soon after engine start. Mine is now set to switch over at 20 deg.C and after 30 seconds running. It still falters a little after 30 seconds but normally I'm up the road by then and it runs quite happily under load.
An idling issue won't have cooked the plugs, though, so the problem is likely to be from running under heavy load IMHO.
Were all the plugs similarly affected?
