COPPER SPARK PLUGS
Guaranteed to deliver quick starts, good fuel economy and smooth acceleration.
Autolite® Copper Core plugs are your industry standard.
• Copper-glass seal bonds insulator, terminal post center electrode together; assures full required voltage at spark gap; gas-tight seal (100% leak proof)
• Multi-rib insulator reduces danger of “flash-over”
• One-piece terminal post adds strength
• Resistor reduces radio frequency interference (RFI) and electrode erosion
• Cold-formed steel shell precision rolled threads
• Full copper core electrode provides better performance in all conditions
