Our expert insights into spark plugs replacement
What do spark plugs do?
They convert electric current from the ignition coil into a spark that ignites the fuel and air mix inside the car engine. This combustion is what powers the engine and moves the car.
Symptoms of malfunctioning spark plugs
If your car struggles or fails to start, or if your engine cuts out after starting or during its usual operation, or if it fails to run smoothly or it vibrates excessively under normal use it could be down to faulty spark plugs.
What happens when we replace your spark plugs?
Our mechanics will check for possible fault codes relating to the ignition system or the spark plugs themselves. Wherever required your spark plugs will be replaced.

Smart
Smart is a German automotive brand, established 25 years ago in 1994.
The company is a division of the automotive corporation Daimler AG and operated under the ownership of Mercedes-Benz.
How popular is Smart in the United Kingdom?
Smart isnt’ the most popular brand in the UK, most likely due to appealing primarily to parking-challenged city-dwellers; there are only 96k of their vehicles on the roads of the UK today.
Showing steady growth, however, since their introduction to the UK market in 2003, the trend would suggest that we’re likely to see more of these eccentric looking tiny cars as time goes by.
Smart: Quirky little microcars and subcompacts
Owned by Mercedes-Benz, Smart cars fit into the market you’d expect on first glance. They’re a fun and funky little city car; they’re solid, middle of the road machines, designed to be as versatile as they look.
A Smart car will never fool anyone that it’s a hi-end, luxury vehicle. There’s plenty of glossy plastic and groovy fabrics, yet in the cockpit, you’ll find up-to-the-minute touchscreen media options at the controls. They do come at an inflated price for the small city car market, but by nature of their unique design—there’s nothing quite like them.
Smart cars are cheap to run—but not so cheap to buy
Your Smart ForFour will be more expensive by comparison than its rivals: the Fiat 500, Skoda Citigo, Kia Picanto or Hyundai i10—yet it’s rather hard to pitch the Fortwo against anything because there isn’t anything on the market quite so small. Only the Renault Twizy comes to mind, and that’s barely a car at all.
Once you’ve got one though, your Smart car will cost next to nothing to run with their tiny wheels and low weight. The electric models perform even better with a fuel equivalent of 87mpg.
How often should spark plugs need replacing?
Most manufacturers recommend that spark plugs should be replaced at around every 30k miles; this is only a guideline, as the quality of the component, engine performance and driving habits can affect spark plug lifespan significantly.
The law, vehicle regulations and your MOT
Old or damaged spark plugs can affect engine performance areas that cause an MOT failure, for example, in emissions testing. Poor performing spark plugs or filters that clog up can affect the gasses that are delivered from your exhaust; replacing these faulty parts can often rectify the problem.
What happens when we replace your spark plugs?
Our efficient and fully qualified mechanics will check for possible fault codes relating to the ignition system, the operation of the ignition system and the spark plugs themselves.
A compression test may be carried out on each of the engine’s cylinders.
Wherever required your spark plugs will be replaced and you’ll be advised of any other connected or associated problems arising from their malfunction.
You will also be advised of any other affected parts that may need to be replaced for the best operation and health of your vehicle.
Once the spark plugs have been replaced, our mechanics will test them thoroughly to ensure their correct operation and make any adjustments required for their optimum performance.
What causes spark plugs to stop working correctly?
Spark plugs can wear out over time, at which point they should be replaced to ensure the correct combustion of fuel. There is also a chance of potential carbon build up on the electrodes; this is known as carbon fouling and will affect the correct operation of the spark plugs. Oil can build up on the spark plugs too, which can be rectified with a simple cleaning.
Spark plugs can occasionally melt due to excessive engine temperatures. This isn’t usually a spark plug fault, but that of the engine or fuel system.
Symptoms of malfunctioning spark plugs
Starting your engine is problematic
If your car struggles or fails to start, it could be down to faulty spark plugs.
Engine cut out or misfiring
If your engine cuts out after starting or during its usual operation, if it fails to run smoothly or it vibrates excessively under normal use, then your spark plugs could be due to worn out spark plugs.
The dashboard engine warning light is illuminated
Any dashboard warning light is due to a sensor detecting fault or incorrect operation of a related component. An engine warning light could relate to a faulty spark plug.
Fuel consumption is higher than normal
Faulty spark plugs can cause your engine to burn fuel in an erratic manner, affecting both vehicle performance and fuel consumption. If you notice a change in your fuel consumption, it could be a spark plug problem.
