If using a plug one range colder than stock gives our trucks
more power and makes them run better, why wouldn't our trucks come with them
from the factory? Emissions? I have the autolite 5224's waiting to be put in.
Does anyone know the part # for plugs one range colder? Are there
anydownsides to going to a plug that is one range colder?
