MSD has produced the best performing and most popular performance ignitions for over 20 years. The high energy spark of the CD (Capacitive Discharge) design combined with multiple sparks resulted in a potent ignition. Not only does the multiple spark discharge (MSD) ignite the lean fuel mixture, it makes overall improvements in the engine's performance! Improved starting, smooth idle, less emissions and more power are benefits every car and truck can take advantage of, especially race cars. Professional Mustang racers learned of the new MSD quickly and soon word spread throughout the racing world. Since then, MSD have gone on to be the ignition of choice of the top professional drivers in NHRA, IHRA, NASCAR, World of Outlaws, DIRT, SCORE, IDBA and many more. MSD products include Mustang Ignition Controls, Mustang Coils, Timing Accessories and Mustang Spark Plug Wires. MSD products are the finest ignition components you can install on your Mustang whether it's a daily driver, a track racer, a seven second Pro Stock car.
