On an average plug, a narrow core typically shortenslife span of plug but with the intense durability of iridium thereis no sacrifice in any longevity. With a high melting point of 2454degrees C, opposed to the degrees C of white gold, theelectrode can tolerate the high levels of compression and minorknocking without any deterioration. A nickel coating on the housingalso prevents the spark plug from premature deterioration. TheIridium plugs are available for multiple applications and offeredin colder heat ranges of 7 and up and specifically for rotary,heat ranges of 9 and up are offered.
