Autolite 2545 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 key feature of these plugs is the copper-glass seal, which bonds the insulator and terminal post center electrode together, ensuring a gas-tight seal that is 100 percent leak-proof.

The copper core electrode provides superior thermal conductivity, resulting in improved performance in all conditions. The multi-rib insulator reduces the risk of "flash-over," preventing misfires, while the resistor helps to reduce radio frequency interference (RFI) and electrode erosion.

Autolite Copper Core spark plugs are constructed with a cold-formed steel shell and precision-rolled threads, as well as a one-piece terminal post that adds strength to the overall design. These features contribute to the improved durability and long-lasting performance of the plugs.
