Iridium Spark Plugs
| HKS Super Fire Racing spark plugs are a series of high performance Iridium spark plugs that are designed for high performance street applications that can handle high levels of tuning and still be able to offer easy start-ups and smooth idling. Utilizing a 0.4mm diameter Iridium plug electrode core and an U-shaped grooved electrode lowers the required voltage for the a spark to occur while maintaining the appropriate gapping, thus providing a stronger ignition spark, a stable idle, and reduces misfires. 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. |  |
