I am going to change my plugs in my 2006 1500 QC SLT 4x4 that has a 4.7 and I need help/opinions on which plugs to put in. I have pretty much narrowed it down to the Champion Coppers or the Autolite 3923's. Any and all input would be greatly appreciated.

 

I've bought a lot of Champion plugs over the years - never bought a good one. Look into the NGKs or Bosch. The NGK might be a 5306. That's the one the Hemi uses. Perhaps the 4.7 uses the same.

 

I'm not totally sure on the 4.7s but, I would stick with NGK, Champion or Bosch...I'm running NGK V-Power and I love them and haven't had any problems. These are the ones that most people are running but, check this out if you have any questions...https://dodgeforum.com/forum/3rd-gen...ark-plugs.html

 

Bosch 7962 are the OEM replacements.
