HEI owners now have a choice to replace their stock coil with the MSD High Energy Unitized Coil for GM HEI Distributors. This coil is a direct re­placement of the stock coil and offers increased spark energy when used with the MSD HEI Module, PN 83647.

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.
