About Spark Plugs

What Is A Spark Plug

A spark plug is what provides the small charge to ignite the air/fuel mixture in your engine. They're relatively cheap to replace, but you want the best quality always to make sure all of your cylinders are firing as they should be. A wide range of spark plugs can be available for every vehicle, from basic spark plugs for your everyday service or replacement, to incredibly advanced platinum spark plugs and iridium spark plugs for use in the world's highest performing cars.

How do Spark Plugs Work?

Spark plugs form the final flashpoint of your engine's ignition system, located at the top of every cylinder to ignite the fuel/air mixture inside at a timed interval and cause combustion. The plugs attach to your engine's ignition coil and distributor, both of which work to share the electrical charge generated by your battery evenly to your cylinders.

Spark plugs are made up of 3 main parts: the terminal, which connects the top of the spark plug to the rest of the ignition; the insulator, generally made out of a ceramic material to insulate the current travelling through it; and the electrode, which is where the spark plug is grounded and in turn, generates the spark going into the combustion chamber. As the years have gone on, the materials that form your spark plug's electrodes have gotten increasingly more advanced. While many standard spark plugs still make use nickel or copper, high-performance spark plugs use noble metals such as iridium, platinum or tungsten.

How can Good Spark Plugs Benefit Australian Drivers?

Dealing with thousands of kilometres worth of driving can be a messy job for a spark plug. As they fire hundreds of times a minute to ignite air and fuel, the electrodes and conductor points on a spark plug can become dirty over time, reducing the ability of the spark plug to efficiently generate a spark. Good spark plugs are built from high quality materials to combat this, ensuring that you get a consistent detonation that is neither too light or too heavy. This means that you can be sure your spark plugs will last and perform reliably between service intervals, saving you time, money and improving fuel efficiency.

As we mentioned before, spark plug technology has developed to utilising space-age materials in the construction of premium and motorsport-oriented spark plugs, and for every engine under the sun. Through the use of these advanced materials, platinum and iridium spark plugs have a much higher melting point, more durability and a better capacity to conduct electricity, in turn increasing your spark plug life and performance.
