Pros
According to literature available on Pulstar's site, Pulse Plugs amplify spark energy internally, leading to a much more powerful spark from factory ignition components than can be found with conventional spark plugs that simply transfer a set amount of power. Amplifying spark intensity can increase combustion efficiency in instances where air and fuel aren't burned completely, resulting in increased power and torque, and increased fuel efficiency.
