Aftermarket ignition ...do you really need one?
My 2 cents is the multi spark ignitions are mileage helpers down low and can help clean up the insides and reduce emissions.
After that, I have found the Chrysler ignitions to be just fine with an upgraded module. When the orange box was a quality unit, it was great for general performance and the chrome box for hot rods. I have a chrome box working 25 or so + years now.
MSD = constant failure.
