We offer a full selection of HKS Super Fire Racing spark plugs for race and tuning applications. The heat ranges are designed to withstand high temperatures and pressures under demanding racing conditions.<\/p>\n

The Super Fire Racing spark\u00a0 plugs are reinforced in ignition capability, durability and anti-insulation. The thermal edge of the ceramic insulator discharges to help decrease carbon deposits under long idling.<\/p>\n

Their iridium alloy center electrode produces a strong spark with reduced voltage requirements, and improves ignition performance and durability.<\/p>\n

The M-series represents a standard “JIS Type” form, with a thread of M14 x 19 and plug wrench size 16 mm \/ 5\/8″, which is a common fitment for many Japanese as well as European engines. They are suitable for both naturally aspirated and turbocharged engines.<\/p>\n

The HKS M-series offers three heat ranges: M35 (NGK 7), M40 (NGK 8) ja M45 (NGK 9).<\/p>\n

The chart below illustrates equivalent Denso and NGK heat range indexes.<\/p>\n
