OEM BMW Spark Plugs
The factory spark plugs in your BMW vehicle are an important part of the ignition process. That's because they generate the small flash of electricity that ignites the air-and-fuel mixture found in an internal combustion engine.
How Your Spark Plugs Work
The spark plugs produce that by firing an arc of electricity across a gap between two leads. The gap is exactly calibrated to manufacture the ideal sparking that's needed to inflame the mist inside your engine cylinder. That leads to pistons pumping, the crankshaft rotating, and the engine power you need. Unfortunately, even the best spark plugs can begin to lag in performance. That affects your ability to start and drive your BMW.
Symptoms of Failing Spark Plugs
Perhaps the gaps have widened too far to produce the effective spark. Maybe your spark plugs have become corroded. Be sure to check the condition of your spark plugs if you notice any of these signs:
- Repeated engine misfires
- The engine idles unevenly
- You have difficulty starting your vehicle
- Your "Check Engine" dash light comes on
Genuine OEM Spark Plugs Are Best
If you're not noticing any problems, check your owner's manual for the recommended maintenance schedule. You don't want to push your original spark plugs past their rated mileage. When it is time to replace yours, make sure to get the right ones for your vehicle. Those are always genuine BMW, since those are the only ones that are guaranteed to be compatible with your model and its engine.
