HKS M-Series Super Fire Racing spark plugs are high performance Iridium plugs designed to handle advanced levels of tuning and provide Improved ignition performance, durability, and anti-carbon build-up.

The Iridium alloy is used because of its durability and reliability. On an average plug, a narrow core typically shortens the life span of the plug but with the intense durability of iridium, there is no sacrifice in any longevity. With a high melting point of 2454 degrees C, as 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. M Series is recommended for reliable ignition, durability, and anti-carbon buildup under high load. All spark plugs are sold individually.
