EC21 and EC20 spark plugs are specifically designed Jenbacher series 6 engines. The new „monocoque“ design was developed to optimize thermal transport out of the electrodes, which leads to longer lifetime. It eliminates a welding joint and increase thermal conductivity of the housing.
Spark plugs for Jenbacher series 6 engines comes in 2 versions. The standard version with an estimated range of up to 4000 running hours and the LL version (for long life) lasting up to 6000 hours or running hours.
