HKS SUPER FIRE RACING SPARK-PLUG M45RE is a super-performance Iridium plugs uniquely engineered 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 a 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 compression and minor knocking levels without any deterioration. Also, a unique nickel coating on the housing prevents the spark plug from premature deterioration. The Iridium plugs are available for multiple applications and offered in colder to 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.
