How does a spark plug work?
A spark plug does exactly what its name suggests: It’s responsible for creating the spark that an internal combustion engine needs to start and run. When electrical voltage is sent to a spark plug, that electricity arcs the small gap between the two electrodes at the firing end, igniting the compressed fuel-air mixture inside the cylinder.
What happens when a spark plug fails?
When a spark plug fails or starts breaking down is when problems occur in other areas of the engine. Often times, you will notice a misfire in the vehicle or it may be difficult to start up. As a car owner, it’s important to identify when these components need replacement, as they can cause serious damage if left unattended.
Do spark plugs need a good connection?
In order to work properly, your vehicle’s spark plugs need a good connection with the distributor cap and coil after they have been installed in an oxygen-free electric environment for 15 minutes or more before installation of new spark plugs.
Is synthetic engine oil good for spark plugs?
A good quality synthetic engine oil can increase the lifespan of a spark plug by ten per cent. Additionally, if there is too much air or fuel in your engine it could cause increased cylinder pressure, which will make the electrodes to wear quicker.
