(3-00403) Genuine BMW M42/M44 Water Pump - Composite Impeller (11510393338)
Genuine BMW replacement water pump with o-ring for all M42 and M44 engines.
The factory pumps have gained a bad reputation over the years for having failure prone plastic impellers. The factory pumps have a life of around 90,000 miles and should be changed as preventative measure. The reality is, the 90,000 mile service schedule is often ignored and the pumps are used until failure. The composite impeller pumps have the advantage of an incredibly lightweight impeller with a consistent shape.
