Small components, big effect – good spark plugs ensure smooth starting and optimal performance
You don't see them, but in every petrol engine they do their work tirelessly every day: spark plugs. With a spark they ignite the petrol-air mixture in the cylinders, which starts your engine and keeps it running. Smooth starting on cold mornings, economical driving and clean emissions – it all starts with the right spark from a good spark plug. At Autobest, we work with high-quality Bosch spark plugs, the same quality that many car manufacturers install from the factory.
The operation of a spark plug seems simple, but is essential for the engine. In each cylinder, a mixture of petrol and air is drawn in. At the right moment, the spark plug gives off a spark, causing this mixture to ignite. The controlled explosion that follows pushes the piston down. The crankshaft is driven via the connecting rod – and this is how your car moves.
This process happens thousands of times per minute, for each cylinder. The spark plug must therefore be reliable and always give off a powerful spark at the right moment. If that doesn't happen, you notice it immediately: difficult starting, irregular engine behavior or even engine failure.
The moment when the spark plug gives off its spark is determined by the ignition timing of the car. In the past, this was done with mechanical contact points that were opened and closed by a rotating rotor. Nowadays, every modern petrol car has electronic ignition.
This electronic ignition works very precisely, allowing car manufacturers to set the timing perfectly for optimal engine performance, economical consumption and low emissions. But that precision only makes sense if the spark plugs themselves are also of top quality.
It's not without reason that many renowned car brands fit Bosch spark plugs as standard in their petrol engines. These spark plugs are known for:
At Autobest, we therefore use Bosch spark plugs. The same quality that car manufacturers trust, you get during maintenance or replacement.
Bosch uses high-quality precious metals such as platinum and iridium for the production of its spark plugs. These materials have an extremely high melting point and hardly wear, which means the spark plugs last longer and perform more consistently.
Examples from the Bosch range:
Bosch Platinum-Iridium spark plugs
With a combination of platinum and iridium, these spark plugs offer a long lifespan and excellent performance, even under heavy conditions.
Bosch Super Plus spark plugs
These spark plugs use innovative yttrium alloy, a technology that has its origins in racing. The result: even better ignition, faster response and optimal engine performance.

Spark plugs are wear parts. How long they last depends on the type of spark plug and your driving behavior. Standard spark plugs last on average 30,000 to 60,000 kilometers, while high-quality precious metal spark plugs often last 100,000 kilometers or more.
Signs that your spark plugs need replacement:
Not sure if your spark plugs are still good? Stop by for a check. We look at the condition of the spark plugs and advise you whether replacement is necessary.
Good spark plugs ensure optimal combustion of the petrol-air mixture. That means not only better performance and more economical driving, but also fewer harmful substances in the exhaust gases. A good spark ensures the mixture is completely burned, releasing fewer unburned residual products.
That's better for the environment, but also for your MOT. During the MOT, emissions are also measured, and bad spark plugs can cause your car to fail the emissions test.
At Autobest, we supply Bosch spark plugs in various versions, for virtually every make and model of petrol car. Whether you have a small city car or a powerful sports engine – we have the right spark plugs in stock or can order them quickly for you.
Replacement of spark plugs is done professionally and according to factory specifications. We also immediately check the ignition cables and coils, so the entire ignition system functions optimally.
