This electric water pump is a direct replacement for BMW’s N20 and N26 four-cylinder turbocharged engines, as found in models like the 328i, 428i, and 528i. We proudly offer the German-made OE Pierburg unit — the same brand BMW uses from the factory — ensuring factory fitment, performance, and long-term reliability.
These pumps are critical to engine cooling, using electronically controlled flow to regulate temperature under varying load and ambient conditions. Unlike mechanical pumps, these operate independently of engine speed, improving thermal efficiency and reducing parasitic drag.
If you’ve experienced fault codes, overheating, or intermittent cooling issues — particularly in hot weather or during start/stop operation — it’s likely time to replace the electric water pump. Replacing with an OE-grade Pierburg unit restores cooling system function with confidence.
