Product Line Details

Autolite Copper Resistor Spark Plugs are positioned as OE-style replacement plugs for everyday service work. The copper core supports quick starts, smooth acceleration, and fuel economy-focused maintenance, while the resistor design helps control electrical noise in ignition systems. Part number 5224 follows the same OE form and fit approach used across many foreign and domestic applications.
