Description
We offer a full selection of HKS Super Fire Racing spark plugs 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 heat ranges are designed to withstand high temperatures and pressures under racing conditions.
Their iridium alloy center electrode reduces voltage requirements and improves ignition performance and durability.
The HKS M-G series spark plugs feature a M14 x 19 thread and a larger plug wrench size 20,8mm / 13/16″.
They are generally found in older or specific applications, including:
- Mitsubishi: 4G63 Lancer Evo IV-VIII and Eclipse, Starion, V6 6G72
- Honda: Accord, Prelude
- Subaru: Justy
- Toyota: Celica, Land Cruiser, MR2, Supra 7M-GTE
