What is the tork for spark plugs on a 5.7 liter chev 4X4
It depends on the type of plugs you are using, each brand spec a different tightness...
I never seen anybody torque a spark plug. It would be very light like no more than 10 ft.lbs. You just lightly snug them up. Careful not to put pressure on the porcelain stem as you could crack it and cause a miss.
I guess there is a chart. Not changing my ways tho...
Install them dry and snug.
Use anti-seize on the plugs when you install them and snug them up by hand.
