Spark plugs ignite the mixture of fuel and air in the air to power your car's engine. Over time spark plugs deteriorate due to wear and tear and deposit build-up, which can lead to misfiring - or even mean your engine won't start. You should check and change spark plugs regularly to ensure they're performing properly - check out our spark plugs range for a replacement for your car.
The ignition system in your car uses an electrical spark (in a petrol engine) to ignite the petrol fumes and get the internal combustion engine moving. Without a working ignition, you're not going anywhere.
There are plenty of parts to an ignition system; spark plugs, glow plugs, an ignition coil, a distributor cap, ignition leads, and many more.
