A metal impeller-equipped water pump has virtually been a mandatory upgrade for BMWs for generations—especially if they are destined for spirited street or track duty. For the E9X, this heavy-duty upgrade was spawned by BMW itself for their coveted GT4 racing program.
This BMW Motorsport piece is a genuine replacement for your standard composite plastic impeller, eliminating all doubt of critical failure by virtue of a much more reliable material.
- For all E9X M3 (S65) equipped vehicles
- Genuine BMW Motorsport component (11518331044)
