Our visit to Federal Mogul offered us the unique experience of being able to get a glimpse of the newest spark plug design. One of the benefits of this trip was that we were able to meet directly with everyone from the engineers to chemists who took us through every step of their design process. Their newest spark plug design is called the Advanced Corona Ignition System (ACIS).
ACIS uses a high-energy, high frequency electrical field to produce repeatable, controlled ionization, creating multiple streams of ions to ignite the fuel mixture throughout the combustion chamber. This design allows for more efficient fuel economy and fewer emissions.
