A spark plug fires the air-fuel mixture in a petrol engine. It sits in the engine and sparks thousands of times a minute. WhatsApp us on 07961 404768 with your registration and we will check which plugs fit your car.
What spark plugs do
A spark plug makes the spark that starts the burn in a petrol engine. The coil steps the battery voltage up, the plug fires across its gap, and the air-fuel mixture in the cylinder catches light. Each plug fires thousands of times a minute while the engine runs, and the gap wears wider with use.
Plugs differ in thread, reach, heat range and electrode material. Copper, platinum and iridium electrodes last for different lengths of time, and the heat range has to suit the engine — a plug that runs too hot or too cold for the engine can foul or overheat. Which plug a car takes is set by the engine, not by the driver.
How to find the right spark plugs
Spark plugs are matched to the engine, and to the thread, reach, heat range and electrode material. Two plugs can look alike and still differ in thread, reach or heat range, so a visual match is not enough. Your registration is the fastest way to check your ignition parts. Or tell us the make, model, year and engine.
If your engine is misfiring, hesitating or hard to start, the plugs are one of the parts to look at — but so are the ignition coils. Tell us what is happening and we will point you at the spark plugs.

Spark plugs work with the ignition coils above them. A misfire can point at either one — the coil page below explains what a coil does and how to check fitment.

Frequently asked questions
Spark plugs are matched to the engine, and to the thread, reach, heat range and electrode material. Start with your registration number. Call or WhatsApp 07961 404768 with your registration and we will check which plugs fit before you order.
The difference is the electrode material, which affects how long the plug lasts. Copper plugs wear fastest, platinum lasts longer, and iridium lasts longest. Which type your car takes is set by the engine — call 07961 404768 and we will check fitment.
Yes. A plug whose gap has worn wide, or whose electrode is fouled, can fail to spark properly, so the engine can misfire, hesitate or run roughly. The coils can also be the cause, so ring us, describe what is happening, and we will point you at the spark plugs.
No. Diesel engines ignite the fuel by compression, not by a spark, so they have no spark plugs. If your car is a diesel, the parts that matter for starting are the battery, the starter motor and the glow plugs — call 07961 404768 and we will point you at the right plugs.
