MSD 8253 Blaster HVC-2 High Voltage Ignition Coil Blue U-Core

The MSD 8253 Blaster HVC-2 Ignition Coil is a high-output, square-body coil engineered specifically for use with MSD 6 Series and SCI Series ignition controls. Built entirely in-house by MSD, this coil is purpose-built for high-RPM, long-duration ignition applications where maximum spark energy and reliability are critical.

At the core of the HVC-2 is an iron U-Core design with a segmented bobbin that delivers superior voltage distribution across the entire RPM range. The bobbin is precision-wound from DuPont Rynite FR946 thermoplastic to generate maximum current output alongside an impressive 44,000-volt peak and an industry-leading 450 mA peak current. The lightning-quick rise time and extended 450 microsecond spark duration ensure a complete burn even under the most demanding conditions.

The blue housing is also molded from high-dielectric Rynite material, offering excellent thermal and electrical insulation. Far-spaced brass primary terminals and a well-isolated secondary tower minimize the risk of cross-fire or spark bleed-off. The entire assembly is encased in a fracture-resistant epoxy compound for superior vibration resistance.
