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.
Over tightening means gorilla tightening it.
Snug it and tighten it to where you feel is enough that it won't come out but not gorilla'd
