Well turned 35,000 in in 10 months , who has changed plugs to platinum or went back with copper?
If changed to platinums , Any problems with platinums plugs ?

Looked on search could not find anything?

 

I have only read that you should put the original plugs back into this all because of the MDS. It was in a forum somewhere. You can put others too that are recommended all your choice.

 

Autolite Double Platinums here at 30K miles. Almost 35K miles now and truck runs like new.

 

The first gen 5.7 Hemi did not like Platinum. 2nd gen, no idea.

 

I remember reading somewhere on these forums that double platinums will work, I will be doing that once I need to change mine.

 

I remember changing my plugs on my old 3rd gen at 45000 miles and the plugs looked new. I think i will wait a little longer on this new one no need to bust my knuckles for nothing. There may be a reason these have to be changed sooner i just can't understand why if they are not bad.
