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.
The 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 MiL-series spark plugs feature a Long Reach M14 x 26,5 thread pattern and a 16 mm / 5/8″plug wrench size.
These plugs fit e.g. the following car models and engines:
- Many modern Toyota, Nissan, Subaru, Honda, Mitsubishi engines (e.g. EJ257, VQ35DE, 2JZ-GTE, 4G63, some 8AR-FTS, 2GR-FE)
- Certain BMW and Mercedes-Benz models
- Some Kia/Hyundai platforms (e.g. 3.3T engines like Kia Stinger)
Three heat ranges available: 35 (NGK 7), 40 (NGK 8) and 45 (NGK 9).
The chart below illustrates the respective Denso and NGK heat range indexes.
