• Copper core in the center electrode for precise control of the heat range.
• Improved performance and longer lifespan of the spark plug.
• Electrodes with fine wire for increased ignitability and reduced spark lost.
• Reduced distances between the shell and the tip of the core for less contamination from carbon deposits.
• Patented SAC-9 resistor for maximum suppression of EMI and RFI.
