There are several aftermarket pumps out there which are superior to the OEM.
This is because the OEM uses a plastic impeller which actually disintegrates over time while the pressed metal impeller on the aftermarket pump lasts the life of the pump (ie bearing). A degraded impeller may not always be the cause of failure, but over time, it is the cause of reduced coolant flow.
When the time comes, I'll go with aftermarket due to it's robustness. The fact that's it's less expensive simply sweetens the deal.
Cheers!
