The Iridium
alloy is used because of its durability and reliability. On an
average plug,
a narrow core typically shortens life span of plug but with
the intense durability of iridium there is no sacrifice in any
longevity. With a high melting point of 2454 degrees C,
opposed to the 1769 degrees C of white gold, the electrode can
tolerate the high levels of compression and minor knocking
without any deterioration. A nickel coating on the housing
also prevents the spark plug from premature deterioration. The
Iridium plugs are available for multiple applications and
offered in “colder” heat ranges of 7 and up and specifically
for rotary, heat ranges of 9 and up are offered.
