My 1987 W124030, spark ignition has a Jacobs Omni Magnum Ignition System.
I requires Copper Cored Spark Plugs to complete the resistance of the individual plug circuit.
The air gap for this system that performs best is 0.054 inches.
Is there a special reason for using these Plat, multi electrode, resistor or whatever is being presented to the auto owner?
All of these new snake oil plugs available to day were here 30 years ago, just in a different box.
So the best bet is what is in your Owners Manual.
