AUTOLITE 4316 Spark Plug 4-4316 Copper

The AUTOLITE 4316 Spark Plug, SKU 4-4316, is designed with a full copper core electrode to support consistent performance in a range of operating conditions. Its copper-glass seal bonds the insulator, terminal post, and center electrode together, helping maintain the required voltage at the spark gap while providing a gas-tight, leak-proof seal.

A multi-rib insulator helps reduce the risk of flash-over, while the one-piece terminal post adds strength. The integrated resistor is designed to reduce radio frequency interference (RFI) and electrode erosion. A cold-formed steel shell features precision-rolled threads for reliable installation.
