So what we do know is that there are differences in plugs, and over tightening can ruin a Nova button head.

So now we use an OS plug in a Nova without "over tightening." What torque value is that?

Not exactly using a torques wrench when replacing my plugs. And when I'm racing and all I have is a glow plug wrench and a quick glow plug change is required, I'm not exactly hoping my mechanic is thinking about how much to torque the plug.

Rather not take the chance.
