MSD 8242 Blaster Coil-on-Plug Ignition Coil 4.6L/5.4L SOHC 2V Red

The MSD 8242 Blaster Coil-on-Plug (COP) is a direct bolt-in performance ignition coil engineered specifically for Ford 4.6L and 5.4L SOHC 2-valve V8 modular engines. Designed as a drop-in replacement for factory coil-on-plug units, it connects directly to OEM connectors with no wiring modifications required.

While the housing profile and mounting footprint match the factory coil exactly, MSD engineers upgraded the internal components significantly. Higher-quality materials are used for both the primary and secondary windings, and a patented winding design with dual magnet technology steps up voltage output well beyond stock levels. The result is stronger, more consistent spark energy delivered directly across the plug gap — improving combustion efficiency and engine output.
