Factory BMW Spark Plugs

A spark plug is a small but essential part of your BMW's engine, responsible for igniting the air-fuel mixture to power your vehicle. When it’s time to replace your spark plugs, it’s crucial to choose genuine BMW parts for reliability and performance. At OnlineBMWShop.com, we offer high-quality spark plugs designed for your BMW, far superior to cheaper, generic aftermarket alternatives.

What Do Spark Plugs Do?

Spark plugs generate the spark necessary to ignite the engine’s air-fuel mixture, allowing your vehicle to run smoothly. They play a key role in your BMW's engine efficiency and overall performance. Genuine BMW spark plugs, such as those used in the 7 Series and X5, are crafted to last longer and perform better than aftermarket options, ensuring reliable ignition and a smoother ride.

Why Do Spark Plugs Break Down?

Over time, spark plugs wear out due to the high heat and pressure they endure inside the engine. They can become fouled by carbon deposits, corrosion, or simply lose their ability to generate a strong spark. Aftermarket spark plugs often degrade more quickly, leading to reduced engine performance and efficiency. If you notice a misfire or sluggish acceleration, a worn spark plug could be to blame.

When to Replace Spark Plugs?

It’s important to replace spark plugs when they show signs of wear or after a specific mileage interval. Always choose genuine BMW spark plugs to avoid the risk of poor engine performance caused by cheap, inferior aftermarket parts. Don’t forget to check related parts such as your air filters to maintain optimal engine health.
