Poor idle, engine misfires, or reduced fuel economy sound familiar? Changing your spark plugs might just be the answer. Over time the electrode will degrade and can see a build-up of carbon which weakens the spark. Spark plugs are responsible for igniting the fuel, so a clean spark is required to ensure you're getting the best performance and fuel economy from your BMW. These platinum spark plugs from original equipment supplier Bosch are made in Germany and feature a quad-electrode design for greater performance and longevity. These are the same spark plugs that BMW fitted at the factory.
