HKS 50003-M50HL M-Series Super Fire Racing Spark Plug

HKS M-Series Super Fire Racing spark plugs feature advanced high performance Iridium construction, offering improved ignition performance, greater durability, and resistance to carbon buildup. Their Iridium alloy is chosen for its strength and longevity - its 2454°C melting point is higher than the 1769°C of white gold, allowing the electrode to cope with higher levels of compression and minor knocking. A nickel coating on the housing further guards against premature deterioration. M Series is ideal for high load applications and is available in a variety of heat ranges - 7 and up for regular and 9 and up for rotary. All plugs are sold individually.
