Spark Plug Torque Requirements

[candrienne]

Need some advice . . . I plan on changing the spark plugs on my '96 Sport truck. Does anyone know what are the torque requirements for the spark plugs. I would appreciate the help on this!

I'd give them a good 1/4 turn after they've seated, but I think proper specs is 20-30 inch-pounds (less than 5 foot lbs)

20 ft/lbs....... between 1/12th and 1/6th turns after the tapered seat contacts the head.

jimmiecakes is the closet. But the actual correct spec. for the 4.0L OHV plugs is 14-20 Nm (10-15 ft-lbs)
