So you're saying that the Motorcraft engineers who decided that the factory parts on Ford vehicles needed an upgrade before they let AMC get the parts are "Tinkerers" "Geeks" and/or "nerds" who didn't know what they were doing and only wanted to "Waste Money"? The factories didn't/don't spend a dime more than necessary for the car to last past warranty, so why would Ford use these parts if they didn't greatly improve the vehicle/s reliability, economy rating, and/or emissions????

8K volts is under ideal conditions, even old 6V point ignitions were able to fire that. What if your jeep is off camber and the carb is flooding? What if it's raining and you hit a large puddle? What about 30k down the road when the plug gaps have opened and the old Hypolon or Neoprene wires are deteriorated and it's damp out?

With these parts, most of them can be scrounged at the local pick-n-pull off early '80s to mid'90s Fords, except that I would recommend new plugs and wires, at least. If you need to change all of the parts during a tune-up anyway, it's very little extra expense.

If you don't want to do it, don't do it! Advise is free, and you are free to do with it as you see fit.
