Autolites cracking
Has anyone else had problems with Autolite plugs cracking? About a year ago my wife'* Bonneville started having intermittent misses when under load in Overdrive. It progressively got worse until it finally threw a code. I checked that cylinder and the plug was carbon scored from a crack in the insulation. Replaced that plug and all was good. Now it is starting to do it again, exact same symptoms. I have 6 new plugs sitting at home waiting to go in there anyway, so if thats all it is so be it, but would there be a reason these keep cracking?

Nope...seen it happen...it is due to wrong angle when tightening the plugs and over torquing. It will create hairline cracks on the insulator. You should always tighten a plug with your fingers first, then use a proper socket or wrench.

Except for this, I have had great luck with Autolite. My Buick has run a couple sets of them with no problems, and for the money, it'* hard to consider going with anyone else.
Just for giggles how about trying the NGK TR55?
