JEGS GM HEI Coils

Keep Your Ignition Firing On All Cylinders

JEGS HEI ignition coils are designed to be used with original GM coil-in-cap HEI style systems, as well as aftermarket ignition systems using the HEI style cap. These coils produce up to 45% more voltage output than an OEM coil and provides a cleaner crisper spark. Compatible with distributors that have red and yellow primary wires. Simple installation-no need to remove the distributor from the engine.
