The ideal, direct-replacement for your stock coil, the MSD HEI Ignition Coil is CARB EO approved and recommended for use with MSD HEI Module and increases your spark energy.
Featuring low-inductance, high-temperature windings – which charge faster to provide increased spark energy, even at higher RPMs – these top-of-the-line replacements are capable of withstanding harsh race applications and the rigors of daily use. This is due to MSD’s premium epoxy-filled construction. It produces full power sparks up to 9,000 RPM with a 70:1 turns ratio and lower primary resistance for higher voltage output.
Your MSD HEI Ignition Coil is supported by a limited warranty.
