BMW 320i Spark Plugs

Your BMW 320i compact sports sedan needs ignition in order to start. That ignition only happens thanks to the spark plugs that deliver the initial flash that combusts the air-and-fuel mixture inside the engine's combustion chamber.

How Spark Plugs Work

That flash is generated when the spark plugs fire an arc of electricity across a gap between two leads located at the plug's head. Those gaps are attuned to provide the ideal spark needed and lead to your engine roaring to life.

How to Recognize Spark Plug Issues

Unfortunately, your spark plugs can start to fail over time. Whether they've grown too corroded or the gap between the leads has grown too wide to generate an effective spark, the symptoms of failure are the same. They include:

  • Your engine begins to misfire
  • You have trouble starting your vehicle
  • Rougher than usual engine idling
  • The "Check Engine" dash warning light comes on
