Spark plug standard is usually used to characterize the thermal characteristics of the spark plug, the spark plug heat value that spark plug insulation body heat absorption and cooling balance, the higher the calorific value. The stronger the endothermic and heat dissipation capacity, the heat value of the hot spark plug is low and the hot value of the cold spark plug is high. General high power, high compression ratio of the engine selection of high calorific value of the cold spark plug; the contrary, low power, low compression ratio of the engine selection of low calorific value of the spark plug. General spark plug selection is the factory through the product stereotypes to determine, should not be replaced.
