The hotter coil does allow you to set the gap wider for better combustion, but not all plugs are designed to accomodate a wider gap. You may have to switch to a different plug, like some of the 5/8 " plugs that have a wider gap right out of the box.

and i will say that this coil is a fantastic mod. So much nicer at idle and cruising (used to pop sometimes), and my plugs are cleaner. Worth the money forsure. Very Happy

single points setup on a 78. since the coil was a 3.3 ohm and thats hard on the points, i used a Ballast Resistor from a 70's dodge truck inline with the primary so bring the resistance up to 4.8 ohms.
