MSD Blaster Coils have different variations and aspects that help with better ignition. MSD8202 is a blaster coil that features improved output coil for a variety of ignitions. It's 100:1 turns ratio and lower primary resistance produce high voltage output and its an upgrade over your stock coil. MSD8222 is the High Vibration Coil that is encased with epoxy to protect winding from high vibrations and is the best choice for off-rad conditions. MSD8252 is associated with the Blaster HVC Coil that is designed for high rpm applications and provides max power to your car that is currently equipped with a MSD 6 unit. It offers spark plug style terminals and threaded brass primary studs. MSD8207 and 82073 allow improved output coil for electronic ignitions and MSD ignitions. 70:1 turn ratio and lower primary resistance produce high voltage output and when paired with a 6 series ignition, the blaster SS produces 300 milliamps of current and a max of 40,000 volts.
