Twin-tip design enables faster flame propagation for more complete combustion
Twin-tip technology with 11 mm platinum center electrode and 11 mm titanium enhanced ground electrode
Improve fuel economy, better acceleration and faster starts than all other single platinum plugs
Copper-glass seal bonds the center electrode and insulator together for a gas-tight seal
Purified alumina powder insulator provides exceptional dielectric strength and thermal conductivity, allowing the material to stand up to extreme stress
