Gapping Spark Plugs
For modern fine-wire spark plugs, you should not measure the gap unless instructed by the manufacturer.
The Evolution Of Spark Plugs
Without the spark plug, there would be no internal combustion engine. The exact date of birth and father of the first real spark plug isn’t known for sure – some credit Edmond Berger with the invention as far back as 1839 but it was unpatented and definitely not designed for a car engine.
Picking The Right Spark Plug
If you understand why the manufacturer specified a particular plug technology, you can pick the correct replacement plug.

Spark Plug Replacement Basics: Removal, Installation And Choosing The Right Plug
Spark plug replacement is often considered one of the least complicated tasks at a shop. But, ignorance of what you are dealing with can get you into trouble before, during and after the new plugs are installed.
Spark Plugs: The Lost Art Of Gapping
For a long time, the copper core spark plug ruled the roads. For under a dollar, you could buy a plug that would fit, but you had to gap the plug the correct distance between the electrodes yourself.
The Science Behind Precious Metal Spark Plugs
The higher melting point of iridium and platinum allows spark plug manufacturers to reduce the diameter of the center electrode. The smaller the diameter of the center electrode, the lower the voltage needed to start the spark. The finer point means that the electrode can absorb heat easier and faster, leading to improved acceleration, fuel consumption and smoother idling.
