Autolite 3923 Copper Resistor Spark Plug
The Autolite Spark Plug is essential for daily-driven modern passenger vehicles utilizing compact engines where the 5/8-inch gex size is standard for installation and removal. This plug helps make sure the vehicle achieves its expected fuel economy and smooth running characteristics during driving. The incorporation of a solid copper core center electrode provides optimal thermal and electrical conductivity, which aids in thermal control and improves resistance to fouling in engines that run hotter due to packaging constraints. Furthermore, the high alumina multi-rib insulator helps prevent flash-over across the ceramic surface, which can lead to misfires under load. The Autolite 3923’s nickel-plated shell is hard-wearing to provide increased strength for extended periods.
