Anybody here got the Ft/Lbs Torque Spec for the Spark Plugs for the 4.7? I'd like to properly torque them down.

On the Hemi, it's 13-15 ft/lbs. Probably the same on the 4.7. Aluminum heads, you know. What many of us use is "finger-tight" plus 1/16th turn.

Tightened them down to 15ft lbs with my Torque Wrench.

The method I use, including the anti seize on the threads.

The problem with t/w here is that if the wrench fails to click or the threads in the head are not 100% you run the risk of stripping out a hole and that could happen very easy! I do mine like mentioned above bottom out and 1/16 of a turn maybe a little more and your good to go.
