Spark plugs for Volkswagen are necessary for your engine to run. They are small pieces for your motor that create sparks that complete the combustion process from the mixture of oxygen and fuel.

How a Spark Plug Functions

Spark plugs are made of a variety of materials. Usually consisting of conductive metals like nickel, platinum, iridium, or copper. They are protected with a ceramic or porcelain insulation, which is the white, body portion of the plug. Connected to the top of your engine's cylinder head, the compression from the piston delivers the right ratio of fuel and oxygen to the spark plugs. The combustion that occurs burns the fuel, which powers the engine and keeps it running.

Signs of a Failing Spark Plug

There are several signs of failing spark plugs. They may begin to fail individually, or within the same span of time. Some signs to look out for if your Volkswagen spark plugs are failing are:

Engine sputtering or surging

Car engine failure at start

Higher fuel consumption

Rough idling or jittering
