Ignition Control Boxes
Having the ability to control your performance ignition system has many advantages. Ignition boxes typically improve combustion by delivering multiple sparks to the plug. Other benefits of a high performance ignition box may include: Quicker ETs, easier starting, reduced plug fouling, more power, timing control and even increased fuel economy in some set-ups.
