What you need to know:
- Spark plugs generate a spark that serves to continuously ignite the compressed air-fuel mixture in petrol engine combustion chambers. They also dissipate heat from the combustion chamber to the cylinder head, in order to prevent localized overheating.
- They ensure controlled combustion of the air-fuel mixture at the right instant.
- Indications of spark plug wear include a ringing sound at low rotational speeds, sooty or oily spark plug facings and melted electrodes.
- If the spark plug insulator tip’s optimum operating temperature range (450°C – 850°C or 840°F – 1560°F) is not maintained, its self-cleaning capacity is no longer assured. This can lead to ignition difficulties.
- If the spark plug is operating too cold (i.e. below 450° C or 840°F), it can cause sooting, increased fuel consumption, starting difficulties, poor cold-starting performance, impaired engine performance and incomplete fuel combustion. The latter in turn can damage the catalytic converter.
- If the spark plug is operating too hot (i.e. above 850° C or 1560° F), it can cause melting, uncontrolled pre-
ignition and fuel combustion. At worst, it can even
result in engine damage.
Opt for the Genuine Part because:
- They ensure efficient fuel combustion, thus reducing environmental impact and fuel costs.
- Highly reliable: Their electrodes provide stable sparking and ensure complete combustion of the air-fuel mixture through rapid flame propagation.
- Their ability to dissipate heat to maintain an optimum operating temperature, their self-cleaning capacity and the use of high-tech materials together ensure minimal electrode wear and high mileage.
- Their low voltage requirement for ignition and the precise distance between their electrodes afford superior engine running performance, quieter operation across the entire rotational speed range, and therefore enhanced driving comfort.
- They are resistant to the build-up of corrosive combustion chamber deposits and withstand high temperatures and fluctuations in pressure.
- Genuine spark plugs featuring optimized heat dissipation are specially adapted to each engine type.
