Spark Plugs

Spark plugs functions:

Spark plugs are crucial to the functioning of a vehicle. Indeed, its function is to create an electric spark which then ignites the compressed air-fuel mixture lying in an engine cylinder. It then removes heat from the combustion chamber. With the right choice between all the varieties of spark plugs, your engine will be able to ignite fuel faster. In addition, a spark plug of quality permit reliable starting, even in extreme weather.

Each spark plug must be able to reliably produce millions of sparks. Latest-generation spark plugs are manufactured using extremely resistant materials and have an excellent lifespan.

At NAPA, we offer a wide range of spark plugs, varying by metals and dimensions. There are copper spark plugs, usually referred as standard, which have a solid copper core and a nickel-alloy coating for the electrode. We then offer platinum spark plugs, which is similar to copper spark plug with a platinum disc. It is a more heat resistant metal than nickel, which gives platinum a longer longevity. In addition, there is the double platinum spark plug, which uses the same component. At last, iridium spark plugs are harder than platinum and last even longer.

What are the signs indicating a faulty spark plug?

After several thousands of kilometres, the electrodes where the spark is produced can become covered with dirt or carbon deposits, causing the spark plugs to become less efficient and resulting in increased fuel consumption.
