The MSD pro power coil is a great choice for short duration applications such as drag racing. The special windings of the pro power coil have extremely low resistance to produce the highest voltage possible with plenty of spark energy when used with an MSD 7 or 8 series ignition control. The coil wire tower rises tall above the primary terminals and uses a spark plug style terminal for a firm connection to the coil wire. The housing is molded from a high dielectric polyester material and a ciba urethane compound adds vibration protection to the coil windings. Vibration mounts are also supplied.
