How much should I torque my spark plug to on a G20

huh... dunno... I just do it until it's tight. When you put on brand new spark plugs, they have the crush washer on them. So it'll screw on really easy at first. Then when it gets to the crush washer, it'll get a little tougher. And then when the washer gets crushed, it'll get very hard. I stop around that point.

Of course, if you're reinstalling a used spark plug, the washer is already crushed so it'll go straight to being very tough. Remember to be careful because you definitely don't want to strip the threads in the block!
