I think that the stock champions are the best for our trucks. I tried NGK's cause thats what I have always ran in everything but they didnt run to great in 360, I also tried the Autolites that are supposed to be good, but they were garbage. I havent tried the Bosh and I dont plan to. Stock Champions are the best route to go in my opinion,

I've always been told that Champions are the best for Dodge and I have many relatives who have been long long time Dodge owners.

I like the NGK V-Powers but can't say they are better in new condition than the stock Champions, but may keep sharp edges longer.

In terms of sparkplugs
the Magnum engines seem to do well with many
as long as the edges are kept sharp.

Cylinders 7 and 8 may need sparkplugs one heat range cooler
than cylinders 1-6

Much sparkplug tech info in the Magnum Engines Sparkplug FAQ in post 15 at:
