Spark plugs?

[JbHemi]

What's going on forum I'm curious as to what are other spark plugs that can be used on the 5.7 Hemi ? Other then the champion stocks I believe they are ? Like a colder spark plug ? ngk? or what not. What plugs do you run an is there any difference vs what's recommended stock.?

Stay with the stock ones, if you run too cold a plug you will get misfire t high rpm. Champion has historically been on the cold side to start, to hot detoniation, the factory uses a speific plug for a reason. If you modify the engine then use a different plug.

I see that he is modified, and probbaly added 100 Hp..generally go one step colder for every 100-150 HP added over stock. I think he s close, My last build was similar, I used stock spark plugs and I was fine as well. If the OP is not having problems with stock, then stay with it!

I mean sometimes it doesn't want to kick over an the starter just keeps kicking over.
