Some coils are 1.7 ohm or 1.5 or near. The stock coil is .7 ohm- and so is the MSD coil. If you use the MSD coil you will increase your voltage and be safe with the stock resistor. I've had the MSD coil with 8mm wires on my car for years, no problems. -----Dani B. #5003 --- In dmcnews@xxxxxxxxxxxxxxx, "sweetp01569" <paul.sweet@xxxx> wrote: > Is there a significant difference with the high performance ignition > coils, versus the stock Bosch coil?
