Autolite 24 Copper Resistor Spark Plug for Automotive (1 Pack)

Autolite Copper Core Spark Plugs are designed to deliver exceptional performance, featuring a full copper core electrode that provides superior thermal conductivity for improved performance in all conditions. These plugs are engineered to ensure quick starts, good fuel economy, and smooth acceleration.

The copper-glass seal, which bonds the insulator and terminal post center electrode together, creates a gas-tight seal that is 100% leak-proof. This design ensures that the full required voltage is delivered at the spark gap, optimizing ignition efficiency.

Constructed with a cold-formed steel shell and precision-rolled threads, Autolite Copper Core spark plugs are built to last. The one-piece terminal post adds strength and durability to the design. Additionally, 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 has been a trusted leader and innovator in spark plug technology since 1936. Their copper plugs are backed by decades of experience and passion, providing performance and value that customers can depend on.
