MSD 8255 Blaster Direct Ignition Coil Gen III HEMI 5.7/6.1/6.2/6.4 Red

The MSD 8255 Blaster Ignition Coil is a high-performance coil-on-plug direct ignition coil engineered for Gen III HEMI engines. Featuring MSD's patented winding design and premium internal materials, this coil delivers a stronger, more consistent spark than the factory unit — improving combustion efficiency, smoothing idle quality, and boosting mid-range RPM power.

Designed as a true direct bolt-in replacement, the MSD 8255 plugs directly into the factory coil connector with no wiring modifications required. The square-body, epoxy-filled construction provides excellent thermal and vibration resistance for long-term durability in demanding conditions. The coil is finished in MSD's signature red and is sold individually.
