How does platinum improve a spark plug?
A. Perhaps the greatest innovation in spark plug design over the years is pure platinum?technology, combined with multiple electrodes. As early as the 1960s engineers recognized the value that platinum added to automotive plugs: it provides improved corrosion and erosion resistance and imparts a longer performance life than the standard copper core center electrode plug design. The use of platinum not only broadens the heat range beyond that achieved with a copper core center electrode design, but also provides extremely consistent performance, a reliable spark and a longer performance life.
