Spark Plug Torque Specs

Go by feel. I do the finger tight (or if its difficult to get to with fingers I do "snug", which is just as soon as you feel any resistance). Then the 1/2 turn to crush the washer if its there. Like others said. Make sure you use anti seize for easy removal later.

Even if they are finger "snug", you're not gunna have problems. The only way you'll have problems is if you only spin the plug 1/4 of the way in.
