HVC Coil For #6600 Ing. Box

The MSD HVC Coil For #6600 Ing. Box is a high-voltage performance ignition coil designed for serious engine builders and street/strip enthusiasts running MSD 6-series ignition systems. This E-core coil delivers reliable spark energy to custom-built, modified, and competition engines that demand precision timing and consistent voltage output. Whether you're upgrading a carbureted small-block, big-block, or building a fuel-injected powerhouse, this coil provides the electrical foundation for maximum combustion efficiency and horsepower.

Built on proven MSD technology, the HVC Coil generates 34,000 volts of peak output—sufficient to fire heavily modified engines and cold-start conditions without misfires. The E-core design minimizes electrical losses while maintaining low 0.070-ohm primary resistance, ensuring efficient energy transfer to your ignition box and spark plug wires. The male HEI connector integrates seamlessly with MSD 6600 and compatible 6-series ignition control boxes, making installation straightforward for both OEM and custom harnesses. Black epoxy construction provides durability against engine bay heat, vibration, and moisture exposure typical in modified vehicle environments.

Mechanics and engine tuners choose this coil for naturally aspirated and forced-induction applications where voltage consistency matters—turbo/supercharged builds, high-RPM carb engines, and custom fuel injection setups all benefit from its stable output. The compact footprint (5.6 × 5.55 × 6.45 inches, 4.39 lbs) fits tight engine compartments without requiring relocation brackets. Replacement or upgrade installation takes minutes; simply disconnect the old coil from your MSD 6600 box and plug in the HVC unit. Verify your harness termination matches the male HEI connector before purchase to ensure compatibility with your specific ignition system configuration.
