RE: best spark plugs?
I like my champion plugs.....alot of ppl will say bosch is garbage...My truck had them in it when I bought it and I never had any problems, but when I changed them the electrode was pretty ate up and the ceramic was chipping offon some andone had a crack all the way through it.

RE: best spark plugs?
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,

RE: best spark plugs?
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
