• Copper-glass seal bonded insulator, terminal post, and center electrode
• Multi-rib insulator reduces danger of "flash-over" to prevent misfires
• Copper core electrode improves heat transfer and optimizes plug life
• Center provides higher thermal conductivity
• High alumina ceramic for high dielectric strength and steel shell for installation robustness
