I want to go ahead an replace the plugs now so I'm not doing this in the dead of winter when its cold.
Any tips or tricks?
What plugs?
I'm a NGK guy but if there is something that the Hemi likes better, I'm game!
Watch the torque with the Hemi plugs and go with OEM coppers. What year do you have? I think 09+ they may have changed the plug spec...
For my 07 I run RE14MCC4, .045 gap and 13 ft-lb torque (do not exceed 15 ft-lb)

Mine is a 09, what is the new spec on the plugs?
best thing to do is look at the placard under your hood. It will tell you the plug spec and gap.

I have been running Autolite Iridiums for almost 80k miles now with excellent results. My Hemi is happy!
