Be careful of people advertising cheap high-volume water pumps, and even cheaper ‘stock’ replacement pumps. There are 3 pumps available new: Cheap junk (notably substandard compared to the OE pumps, sold by many as ‘OE replacement’), high quality stock replacement (sold by us and some others as ‘stock replacement’, but sold incorrectly as ‘high volume’ by the unscrupulous, simply because they are better than the cheap not-so-great replacement pumps), and true high volume pumps, which are only made by FlowKooler. The FlowKooler pump features a trick billet brass impeller that pushes roughly 30% more coolant at idle than the factory and high quality replacement pumps. The factory and high quality replacement pumps push nearly that much more at idle than the cheap junk replacement pumps. Looks can be deceiving, but if it’s not a FlowKooler, it’s not high volume.
