Ford Expedition MSD Ignition Products 

It always impresses us when a company is able to effectively solve a technical barrier, and in the process ends up creating something that not only works, but solves other problems as well. MSD Ignition was developed to solve a weak spark condition that presented itself when Autotronic Controls Corporation (MSD's parent company) invented the lean-burning Electrasonic Fuel Induction system, which was designed to improve fuel economy. With the MSD unit's capacitive discharge design firing off multiple sparks during combustion (MSD stands for "Multiple Spark Discharge," by the way), not only was the lean air/fuel mixture able to ignite, but it also improved starting and idle, and it also created more power with fewer emissions. Today, MSD Ignition is considered the undisputed leader in the field of performance ignition parts, and offers everything from individual ignition components to complete systems.
