OEM Volkswagen Spark Plugs Online

Spark plugs are responsible for igniting the mix of oxygen and fuel inside your Volkswagen vehicle's engine, in a process known as spark ignition. How it works isn't that complicated.

When you turn the ignition key, or press the "Start" button in newer models, an ignition switch activates. Your car battery, starter motor, starter solenoid, and ignition coil work together to produce a small electric charge. The plugs capture that charge and shoot it across a gap between their two leads. The mix inside the engine combusts, the pistons begin pumping, the crankshaft starts turning, and you're ready to head off.

Unfortunately, spark plugs can't last forever. They can grow corroded or break. The leads can get too far apart or rust, making it harder for them to conduct the electricity. Broken plugs are the greatest danger, since they can damage your engine cylinders.
