Water pump AISIN or OEM BMW

My 330i started throwing codes around 135k. Replaced it for peace of mind and it turned out to be the original. I’ve heard somewhere that the water pump used in the 2006 325 and 330i is a bit different and lasts longer

Original water pump, lasted to 167k!

My experience with the N52 was great honestly. I owned a 2007 328i from 2007-2019 and put over 120,000 miles on it. The only engine issues it had were the water pump failing at 90,000, and the oil filter housing gasket leaking.

Well made, but they ain't cheap. Here's the diagrams for the N54 setup: http://www.realoem.com/bmw/par...fg=35 The water pump itself is over $500.
