Spark plugs are an often overlooked maintenance item on most cars. As spark plugs fire, they wear down their electrodes. This wear accumulates over a long enough time that the spark plug gap increases to the point of inefficiency. When this occurs poor performance, lack of power and drivability is decreased. The fuel economy is also likely to suffer. Spark plug replacement is the cheapest and simplest replacement you can do to restore power to your BMW.
