MSD HEI Coils
MSD HEI coils increase spark energy when used with MSD HEI HEAT modules. Now you can replace your stock coil with these high-energy unitized coils for HEI distributors. They have low-inductance, high-temperature windings which charge the coil 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.
