In most cases, the motion of a car is the result of combustion that occurs inside the engine. What triggers the reaction is the spark plug – a tiny device that creates an electrode gap to ignite the mixture of air and fuel in each of your car’s engine cylinders. Fairly durable, spark plugs work in a very severe environment while creating the spark over and over again. Because of that, the device (to be precise, its electrodes) sustains normal wear. Besides, improper burn of fuel in the chamber can wreak havoc on spark plugs. This may be caused by oil penetrating through the piston rings or poor-quality fuel.
Spark plugs do not fail at once – it’s a gradual process. For that reason, it's possible to drive for a while with a malfunctioning spark plug, though it is generally not recommended as severe cylinder misfires cause incomplete fuel burn and consecutive damage to your catalytic converter. What should alert you of a failing spark plug in your Audi A8 is rough cold start, uneven idling or unsteady acceleration due to misfire. The dying plug may also trigger the check engine light. Get the right replacements for your executive sedan in our Audi A8 spark plugs range, which includes exclusively high-quality spark plugs from aftermarket and OE manufacturers.
