What is spark plug?
A spark plug is something your car won’t start without. It is what creates the ignition to combust the fuel that powers your car engine. Although they are made up of very durable materials and can withstand the extreme “heat” of the explosions for very long – millions of times ideally – but the ignitions do cause some wearing and corrosion over time, leading to weaker sparks which can in turn lead to bad fuel economy.
Why are spark plugs plated?
These spark plugs can be thrown away or recycled in the same way as other spark plugs because they’re still very inert and won’t cause a lot of problems to the environment.
What is the outer material of spark plugs?

How long do nickel chromium plugs last?
Many nickel-chromium plugs need to be replaced every 20,000 to 30,000 miles, depending on wear and the specific plug, but noble metal plugs can last for more than 100,000 miles.
What metals are used in spark plugs?
Many spark plug manufacturers are producing plugs that use “noble” metals for their electrode coatings rather than nickel-chromium, primarily platinum and iridium. Some even use the noble metals for the core of the plug.
Why is oxidation important in spark plugs?
Consistent performance over a long life. Given the durability of these metals, the gap between the two electrodes should remain fairly constant, which will make the spark consistent.
Why do plugs have multiple electrodes?
Manufacturers have started producing plugs with multiple side electrodes to help extend the life of the center electrode by encouraging sparking from multiple points. Wearing of the central electrode reduces the strength of the ionization and increases the amount of voltage required to create the spark.
Why does a spark plug have a gap?
The gap between the two of these determines how hot the spark will be because it affects the amount of electrical potential that is required to overcome the resistance of the air. This spark ignites the air-fuel mixture in the cylinder, and the lifeblood of the car is created.
When were spark plugs invented?
True spark plug experts will argue that the design dates back to 1839 to Edmond Berger’s experimental project that was never even patented. We thought the same thing until we stumbled on an article over on E3 Spark Plug’s Website.
How could a 40 year old spark plug get inside a half million year old rock?
So, how could a 40-year-old spark plug get inside a half-million-year-old rock? Skeptics say that the rock may not be a genuine geode but a much more recently formed rock. And even if it is a geode, it might have been covered in mud and clay sometime between the 1910s and 1930s, picked up a few hitchhikers as it rolled along and finally hardened in the California sun, baking the spark plug, nail and washer into its outer, much younger layer.
Is the Coso Artifact the oldest spark plug?
Unfortunately, we may never know for sure whether the Coso Artifact is in fact the world’s oldest spark plug and proof of ancient technology much more advanced than previously thought, or a simple geologic collision of the old and not-so-old. Attempts over the past few years to reach the Coso Artifact’s owner and its original finders have failed and no one else knows where the artifact is today. In any case, we at E3 Spark Plugs bet you’ll never look at a spark plug the same way again.
