Performance Mods - Engine - 5.9 Liter V8
I have a 1984 Power Ram. I'm going to replace the plugs and probably the wires. So the question, is what plugs do the best in a 5.9L out of my 84? Also, would it be worth upgrading the wires to an 8mm or bigger? It's pretty much stock as far as I know. Love some help!
