Autolite Copper Core Spark Plug, Non Resistor

<h1> Autolite Copper Resistor Spark Plug</h1> <p> Autolite Copper Core spark plugs deliver quick starts, good fuel economy, and smooth acceleration. The copper-glass seal bonded insulator, terminal post, and center electrode ensure a tight seal that is 100 percent leak-proof, and the full copper core electrode improves heat transfer and optimizes plug life.</p> <p> Copper Core spark plugs feature high alumina ceramic for high dielectric strength, and a steel shell for installation robustness. The multi-rib insulator reduces the danger of "flash-over" to prevent misfires, and the copper core center electrode provides higher thermal conductivity. These spark plugs are engineered with a high nickel alloy center and ground electrode for extended life.</p> <p> <strong>Features and Benefits:</strong></p> <ul> <li> Copper-glass seal bonded insulator, terminal post, and center electrode provide a tight seal that is 100 percent leak-proof</li> <li> Multi-rib insulator reduces danger of "flash-over" to prevent misfires</li> <li> Full copper core electrode improves heat transfer and optimizes plug life</li> <li> Copper core center electrode provides higher thermal conductivity</li> <li> Features high alumina ceramic for high dielectric strength and steel shell for installation robustness</li> </ul>

• 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
