Autolite 145 Copper Resistor Spark Plug (1 Pack)

Autolite Copper Core Spark Plugs: Delivering Optimum Performance and Durability

Autolite Copper Core Spark Plugs are engineered to provide quick starts, good fuel economy, and smooth acceleration, making them the industry standard. Featuring a copper-glass seal that bonds the insulator and terminal post center electrode together, these spark plugs ensure a gas-tight, 100% leak-proof seal, delivering the full required voltage at the spark gap.

The copper core electrode of these spark plugs offers superior thermal conductivity, providing better performance in all conditions. The cold-formed steel shell and precision-rolled threads, combined with a one-piece terminal post, add strength and durability to the plugs.

Designed to enhance efficiency and longevity, the multi-rib insulator reduces the risk of "flash-over" to prevent misfires, while the resistor minimizes radio frequency interference (RFI) and electrode erosion. These features work together to make Autolite Copper Core spark plugs the reliable choice for maximum performance.

Autolite has been a trusted leader and innovator in spark plug technology since 1936. With decades of experience and a passion for innovation, the company offers copper plugs that deliver unparalleled performance and value, backed by a commitment to quality and customer satisfaction.
