BMW ILZKBR7B-8DG Spark Plug - NGK 97968

If your engine is hesitating or misfiring, it could be due to aged spark plugs that are past their service life. Did you know that as the spark plug fires it actually wears down the electrode increasing the spark plug gap? This is why old spark plugs often perform similarly to misgapped spark plugs. If you are experiencing poor performance and fuel economy, replace your spark plugs and restore performance.
