Run, do not walk away from this plug. Great profit margins for the seller.

Note: Bosch, Champion, NGK all are "OEM" to BMW and have been for years. The 4.8is came with NGK fine wires from the factory, 6 cyl came with either Bosch multiple prongs or single depending on the year and source at the time of production. US BMW Parts & Service uses Bosch and NGK. Europe has all three.

On the other end of plug technology spectrum there are fine wire plugs that use precious metals to allow long life and increased performance over the life of a plug. Life span of plugs: 60-100K, What type of engine RPM, load, and fuel usage will determine life span. Most users wouldn't know the difference between old plugs at 80K VS new plugs. Use these NGK plugs and you will never look back as they will perform all day long, provide good idle, tip in acceleration performance, and will burn everything in the cylinders. What more can you ask from a plug?
