Autolite 388 Copper Resistor Spark Plug
Description
The Autolite 388 Copper Resistor Spark Plug delivers reliable ignition performance for everyday driving conditions. Copper core construction provides strong thermal conductivity, helping regulate electrode temperature through thousands of combustion cycles. A built-in resistor suppresses radio frequency interference, keeping onboard vehicle electronics and radio signals free from disruption. Quick engine starts, good fuel economy, and smooth acceleration all depend on a spark plug that fires consistently, and the 388 is designed to do exactly that. The plug fits as a direct replacement in compatible vehicles, allowing straightforward installation during routine maintenance intervals. Autolite identifies the plug under manufacturer part number 388 for easy cross-referencing at the parts counter.
