It takes a specially engineered coil to handle the 44 amps supplied by the Pro-Mag generator. This coil steps up the current to as much as 45,000 volts while sending over one amp a cross the plug gap. This high voltage is required to initialize the spark when it's up against nitro and extreme boost pressures. Show more
