Spark Plugs at Halfords

Spark plugs are found in petrol engines. Their job is to ignite the fuel-air mixture within your cylinders, in order to start your car and keep it running. Spark plugs gradually wear out, so from time to time they may need replacing.

Luckily you can use our handy spark plug lookup tool above to find the right spark plugs for your car. Simply enter your registration number, and you'll be taken to the best spark plugs for your make and model.

Spark plugs can be reserved online and collected from your local store. Alternatively, you can opt to buy car parts online and have them delivered to your home or place of work - whatever is best for you.

If you need some help installing the spark plugs, take a look at our guide on how to fit new spark plugs for some handy hints & tips. If you've got a diesel engine, you can use our glow plugs lookup tool to find the right set for your vehicle..
