Description
We offer a full selection of HKS Super Fire Racing family of spark plugs optimized for race and tuning applications, featuring reinforced ignition capabilities, durability and anti-insulation. The thermal edge of the ceramic insulator discharges to help decrease carbon deposits under long idling.
Their iridium alloy center electrode reduces voltage requirements and improves ignition performance and durability.
Heat ranges are designed to withstand high temperatures and pressures under demanding race conditions.
HKS Mi-series spark plugs comply with ISO-stds. and represent the universal JIS-type with a thread M14 x 19 and plug wrench size 16 mm / 5/8″ common in Japanese engines and many European car models, such as:
- Toyota engines (e.g. 1JZ-GTE, 2JZ-GTE, 4A-GE, 3S-GTE
- Subaru EJ series (e.g. EJ207, EJ205)
- Honda enginesĀ (e.g. B18C5, K20A2)
- some Audi, BMW, and Porsche models.
They are offered in three heat ranges: 35 (NGK 7), 40 (NGK 8) and 45 (NGK 9).
The chart below illustrates the respective Denso and NGK heat range indexes.
