Durability is ensured by alloying the central electrode with ruthenium.

The center electrode diameter set at 0.6mm reduces the required voltage and improves ignition performance. (Stock: 0.8mm)

Ground electrode with platinum alloy tip improves durability and ignitability. Shortened ground electrode length contributes to electrode strength and durability.

The ground electrode contains a copper core to suppress temperature rise of the electrode and improve durability.
