Racers have been torn on whether to get an inductive or capacitive discharge ignitions. MSD has come out with the solution with the MSD 10 Ignition Control. It produces powerful sparks with combining the best of both ignitions by using two different coils. This ignitions uses the powerful fast voltage of the Pro Power Coil to ionize the plug gap then the Pro Power Couple Coil sustains the spark with a high current. The spark duration is capable of lasting 30° of crankshaft rotation. This will ensure complete combustion under the most extreme cylinder pressures. Also featuring a built-in Two Step Rev Limiter to set a launch rpm limit, quick launches and still have an engine overrev protection. Comes complete with both coils and 8.5mm Super Conductor Coil Wires.
