DESCRIPTION

The S54 engine found in the E46 M3 is one of BMW's greatest acheivements. It's a masterpiece of mechanical engineering, and helped to make the E46 M3 one of the greatest sports cars of the 20th century. But 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 maximum performance and best fuel economy from your M3. Replace your corroded plugs with these original equipment spark plugs from Germany's Bosch.
