MSD is excited to offer blaster coils for late model Ford engines with coil-on-plug technology. The new blaster COPs are designed as a direct bolt-in replacement coil for many SOHC Modular Motors. The housing and installation are the same as the factory, but that’s where the similarity ends. Inside the MSD red housing, engineers spec’d better material to assemble the primary and secondary windings. There is also patented dual magnet technology to step up the output. Together, this combines a coil that produces higher voltage and spark energy. The coil-on-plug design of the blaster COPs puts the spark energy right out of the coil and across the plug gap to improve the combustion and output of the engine. The blaster 2 COPs are available individually or as a complete set of eight.
