Autolite 3926 Copper Resistor Spark Plug (1 Pack)

Autolite Copper Core Spark Plugs are designed to deliver a range of benefits, including quick starts, good fuel economy, and smooth acceleration. The unique copper-glass seal bonds the insulator and terminal post center electrode together, ensuring a gas-tight, 100% leak-proof seal that provides the full required voltage at the spark gap. This innovative construction creates a reliable and efficient ignition system.

The spark plugs feature a cold-formed steel shell and precision-rolled threads, as well as a one-piece terminal post that adds strength and durability. The multi-rib insulator helps to reduce the risk of "flash-over," preventing misfires, while the resistor reduces radio frequency interference (RFI) and electrode erosion.

At the heart of these spark plugs is the full copper core electrode, which provides superior thermal conductivity for enhanced performance in all conditions. This design ensures maximum performance, with the copper core delivering better results compared to traditional spark plugs.

Autolite's commitment to quality and innovation is evident in the construction of these spark plugs. The internal seal is heat-fused, ensuring long-lasting durability and a leak-proof design. This attention to detail and engineering excellence has made Autolite a trusted leader and innovator in spark plug technology since 1936.

The Autolite Copper Core Spark Plugs offer a comprehensive solution for drivers seeking improved fuel efficiency and engine performance. With their quick starts, better fuel economy, and smooth acceleration, these spark plugs are designed to provide the ultimate in automotive replacement technology. Backed by decades of experience and a passion for innovation, Autolite continues to deliver reliable and high-performing products that meet the demands of modern vehicles.

In conclusion, the Autolite Copper Core Spark Plugs are a testament to the company's commitment to quality and innovation. With their advanced features and superior performance, these spark plugs are the industry standard, delivering the ultimate in ignition system reliability and efficiency.
