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

    If you're not experiencing trouble, consult your owner's manual to determine your recommended maintenance schedule. Replacing your spark plugs before they pass their mileage rating ensures consistent performance. When you do need to change yours out, choose the best spark plugs for your car: authentic BMW. They're the only ones that were designed to fit right into place, delivering the compatible fit and quality performance you demand. Find them right here in our online auto parts catalog, and priced well below the MSRP that other dealers command. Buy today and we'll get your order shipped right out!
