BMW Spark Plug NGK 12120022902KT2 M3, Z3, Z4

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 where the spark plug gap increases to the point of inefficiency. When this occurs poor performance, lack of power, and drivability is decreased. 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.

This NGK spark plug is the same spark plug that BMW used and specced for your S54 powered BMW. Additionally, it is the same spark plug that BMW's dealer network uses when servicing S54 powerplants.
