About Spark Plugs & Glow Plugs

As one of the most commonly replaced parts in your car as part of any service, choosing the right spark plugs and glow plugs is vital to make sure your vehicle's engine is functioning as powerfully, efficiently and cleanly as possible.

How Your Ignition Works

Spark Plugs and Glow Plugs essentially play two roles in your car. First of all and most importantly, the plugs chief job is getting your vehicle started in the first place by providing the initial combustion that get your engine turning. In the case of a petrol engine, your spark plugs also provide the spark associated with igniting the fuel/air mixture in your engine's cylinders. Obviously, this is vital to keep you moving.

In order to provide this spark, your ignition system runs from your battery all the way through to your combustion chamber, carrying the charge each step of the way. The current is eventually fed into your distributor, which distributes the charge to each individual spark plug as the cam inside rotates. As the cam hits the point of contact for each individual spark plug, the charge is sent down the ignition leads which connect the spark plug to the distributor, causing them to fire.

The ignition system is slightly different in a diesel powered car, as they don't require the use of spark plugs to make the engine fire (it relies on compression instead), for this reason, diesel ignition systems use glow plugs that heats up and provides the first combustion of the diesel fuel, getting it turning and compressing by itself.
