Hotter Coil

[DaGr8Tim]

What kind of difference does a hotter (performance) coil give (if any)?

I discovered that the coil from an 87 5.0 Mustang had the same replacement part number as my car. In you gentlemen's vast experience, would this make a difference?

On a Tempo, none whatsoever. You already have a very capable ignition.
