Re: 4.0 and 4.0 ho. What\'s the diff?
Jacobs does not have a reputation for reliability, nor for creating a "hot spark." The advertising hype says one thing, testing the actual ignition system shows something quite short of it.
Yes, if you old ignition has problems then of course the Jacobs will be better - because it replaces the defective part(s.) They are about as powerful as a Pertronics, slightly hotter than stock.
MSD!
