Autolite 4164 Spark Plug 4-4164 Copper

The Autolite 4164 Spark Plug, part number 4-4164, features a full copper core electrode designed to support consistent performance in varied operating conditions. Its copper-glass seal bonds the insulator, terminal post, and center electrode together to help 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. The cold-formed steel shell includes precision-rolled threads for dependable installation.
