: The 98% pure copper core provides superior heat dissipation and thermal conductivity. Copper's excellent electrical and thermal properties allow the spark plug to operate across an ultra-wide heat range, making it suitable for diverse driving conditions. Additionally, copper enables extended electrode projection, which positions the spark deeper in the combustion chamber for improved flame kernel development. denso 5285

: A critical safety and performance feature is the internal glass seal that bonds the center electrode, center shaft, and insulator together. This heat-fused seal creates a 100% gas-tight barrier—ensuring that combustion gases cannot escape past the spark plug terminal and that the plug delivers full required voltage to the spark gap. copper enables extended electrode projection
