Blaster HVC-II Coil

The MSD IGNITION Blaster HVC-II Coil (SKU MSD8253) is a high-voltage performance ignition coil designed for serious enthusiasts who demand reliable spark delivery and maximum voltage output. This coil serves applications where stock ignition systems fall short—classic cars, high-compression engines, and custom builds requiring superior spark intensity. The Blaster HVC-II is engineered to handle the electrical demands of modified and restored vehicles where consistent, powerful ignition is critical to engine performance and reliability.

Built around MSD's U-Core design, the Blaster HVC-II Coil delivers 44,000 volts of output energy—substantially higher than conventional coils—enabling faster spark rise times and more complete combustion across broader RPM ranges. The 0.160 ohm primary resistance specification is optimized for efficient energy transfer while minimizing heat buildup during extended operation. The male HEI connector ensures direct compatibility with HEI distributor systems, eliminating the need for adapter harnesses. The coil's robust blue epoxy construction protects internal windings from moisture, vibration, and thermal stress, extending service life in demanding underhood environments.

Restoration specialists, street rod builders, and performance enthusiasts working with HEI-equipped vehicles will benefit most from this coil's voltage capacity and reliability. Installation is straightforward for any vehicle using HEI distributor systems—the male connector plugs directly into the distributor cap tower without modification. Whether upgrading an aging original coil or replacing a failed unit in a classic car project, the Blaster HVC-II Coil provides the electrical performance necessary for dependable cold starts, smooth idle, and consistent mid-range throttle response. Each unit ships ready to install with no additional components required.
