About the Copper Resistor Spark Plug Line

The Autolite Copper Resistor Spark Plug line combines copper core electrodes with resistor technology to reduce radio frequency interference while maintaining strong spark energy. This balance supports smooth engine operation and helps protect sensitive electronic components in vehicles like the Dodge Ram 3500 and Ford Econoline series.

Detailed Product Description

The Autolite Copper Resistor Spark Plug 124 features a copper core center electrode that enhances thermal conductivity and spark efficiency. The nickel-tipped electrodes provide wear resistance, while the tapered ground electrode tip design ensures consistent spark exposure. The resistor built into the plug reduces electrical noise that can interfere with vehicle electronics. With a ceramic short insulator, this spark plug withstands high temperatures and electrical stress. Its 0.438 inch reach and 18 mm thread diameter make it compatible with a variety of Dodge and Ford trucks and vans, including the Bronco, F-150, and E-350 Econoline models.
