Warning: On choosing the right racing plug
  • Generally, electrodes that project into the combustion chamber have better ignitability and have better performance. However, because of more exposure to high temperature combustion gases and because ground electrode becomes longer, heat resistance and durability decrease. The higher the level of tuning, the greater the need is to use a less projecting type.
  • As the level of tuning is increased, so does the need for a higher heat range.
