>Not true, unfortunately. You need to know if your car needs an internal or
external resistor coil. Often, the resistor isn't obvious - it's a piece of
resistive wire in the wiring harness (you sometimes find it when the smoke
leaks out if it ;)).

>The voltage rating of a coil is really the potential voltage - no pun
intended. A coil gives only the voltage required to cause the spark to
form. If 10,000 volts is enough, then even a 50,000 volt coil will only
develop 10,000 volts to form the spark. A higher voltage is sometimes
required in high compression engines, or excessively lean or rich mixtures,
etc. sometimes you can cure a misfire by getting a higher voltage coil, and
opening up the spark plug gap to cause the voltage required to form the
spark to be greater, and so on. But all things being equal, I've always had
good luck with the stock coils, even on race engines.
