MSD 8252 Blaster HVC High Voltage Ignition Coil Blue E-Core

The MSD 8252 Blaster HVC Ignition Coil is an E-Core, high voltage coil engineered for high-rpm, long-duration performance applications such as road course and circle track racing. Designed to pair with MSD 6-Series ignition controls, it delivers up to 42,000 volts of maximum output with a 300 mA peak current and 200 µS spark duration — providing consistent, reliable ignition under the most demanding conditions.

Unlike conventional coils that sacrifice voltage for current or vice versa, the Blaster HVC is built to maximize both. Its 100:1 turns ratio combined with extremely low primary resistance (.02 ohms) enables exceptional voltage output, while the efficient E-Core design minimizes energy loss and helps the coil run cooler even at sustained high rpm.

Key Features:
