OEM BMW Spark Plugs & Glow Plugs

The spark plugs in your BMW car or SAV are a critical part of your vehicle's ignition process. They're the component that delivers the flash of electricity that combusts a mixture of air and fuel.

How Spark Plugs Work

It all starts with you turning the key in the ignition cylinder, or pressing the "Start" button if your vehicle's equipped with one. That activates the ignition switch, which causes your battery, starter motor, starter solenoid, and ignition coils to produce a small electric charge. Your spark plugs capture that charge in their leads and use it to fuel combustion inside the engine, producing the power you need to motor down the road.

How to Spot Failing Spark Plugs

Spark plugs can go bad over time, however. Whether they've grown corroded or the gaps have widened too far, they can't produce the effective sparking your engine needs. Signs of trouble include:

• The engine misfires
• Problems starting your vehicle
• Rougher than normal engine idling
• The "Check Engine" dashboard light comes on
