Best Spark Plugs For Audi S4


Spark plugs are an important component of the automobile’s ignition system. They give off a spark that helps to start the air-fuel mixture within the engine, resulting in the chain reaction that generates vehicle power.

The ignition coil causes electricity to flow through the spark plug, converting it into a powerful spark within the engine. The air-fuel mixture is ignited, generating power.

When spark plugs wear out, the engine will suffer. The check engine light will come on, and it might appear either solid or flashing. One or more of the following may be observed: Engine vibrations, rough idling, reduced miles per gallon (or stall/fail to start), long cranking time needed to start the engine (or surge), and power loss or surging are all possible signs of failing spark plugs. In extreme situations, the engine may cease operating or refuse to start altogether.

Can I drive with a spark plug problem?

When a spark plug goes bad, the vehicle will run, but it is not advisable to continue driving in this manner. Unburnt fuel from the engine will enter the exhaust at a higher rate if a spark plug isn’t working, causing issues for the catalytic converter. If unburned fuel damages the converter, it will result in an expensive repair.

How often do spark plugs need to be replaced?

Spark plugs do eventually wear out, and failure is most common after 50,000-100,000 miles of use under normal driving conditions. But that can be greatly shortened by harsh conditions or leaking fluids.
