The Petronix Igniter was very reliable for me but the coil wasn't. I went through three of them in a matter of three years.
Seemingly though you can't kill the Ford yellow top coil.
In my case, my car has about 22,000 original miles on it. A standard set of Ford points easily will give you 30,000 miles. It takes about 15 minutes to install a new set.
What exactly is this additional dependability that you are attempting to install in your car? In my view, that's just a fantasy. Something that Petronix is trying to convince you of?
I went back to points and the yellow top. Now, I don't need to carry an extra Igniter in the trunk just in case.
You didn't know about that did you? Ask Petronix owners why they do that?
