GM HEI Distributor Coil
This coil is a direct replacement of the stock coil and offers increased spark energy when used with the MSD-83647 HEI Module.
The coil features special low inductance, high temperature windings which charge faster to give you increased spark energy at higher rpm. The premium epoxy filled construction is designed to withstand harsh race applications as well as the wear and tear that daily usage dishes out, and still deliver more spark energy to the spark plugs.
