MSD 8251 Ignition Coil

The Pro Power HVC Coil is designed for racing applications with an MSD 7 or 8-series ignition control.;

Coils have always had to compromise voltage output against current output. More voltage increases the initial ionization of the spark plug gap, but lowers the amount of current, or heat, that follows across the plug gap. When a coil is designed to produce more current, the voltage output generally suffers which taxes the ease of ionizing the gap. The MSD HVC Coils are designed to produce maximum voltage and energy!;
