What's the torque spec on spark plug for the 3.9L?

30 ft-lbs.

30 ft-lbs.

I'm gunna take a wild stab in the dark....and say that the same 30 ft-lbs could be used on the plugs for the 4.7L engine...

I’m not sure what the number is but I am sure it is not 30 foot pounds. Your 4.7 has aluminum heads while the others are cast iron.

Okay I was just making sure because it says somewhere here that the 4.7L is 20lbs.
