OEM VW Spark Plugs

Spark Plugs at a Glance

Spark plugs help start your Volkswagen. Their job? Capturing the electrical charge used to ignite the mixture of oxygen and fuel inside its engine. Ignition itself, however, is an aptly named process called spark ignition.

What is Spark Ignition?

The process starts with the ignition lock cylinder when you turn your key. An ignition switch triggers. The battery, a starter motor, a starter solenoid, and an ignition coil then work together to generate the above-mentioned charge. The plugs' leads capture it; combustion occurs, and the engine's pistons pump, its crankshaft turns, and the vehicle's many systems run.

Unfortunately, though, not even the best spark plug lasts forever. Leads can corrode or excessively widen, reducing their conductivity. Plus, spark plugs can break -- a worst-case scenario that, more often than not, leads to severe and costly engine cylinder damage.

Luckily, if you're worried that yours are failing or have gone bad, there are signs to look for.

Symptoms of Failing or Bad Spark Plugs

• Hard startups
• A misfiring engine
• Acceleration problems
• Rough idling
• Worsening fuel economy

Seeing any of them? Do an engine inspection. Change any spark plugs its results call for replacing. Otherwise, be sure none of them go past the mileage limits recommended in your owner's manual.
