HKS Iridium Spark Plug

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.
