Metal impeller versions are NOT an upgrade, there is no upgrade to the current oem pump.
There are some cheap models on the market with metal impellers that are prone to leaking, reported here on the forum.
Also, our cars do not have silica in the coolant to protect metal impellers against cavitation, which plastic impellers don’t need.
The original plastic ones last very long, so that would still be my choice.
PS Only the very 1st plastic models from 97/98 where prone to failure...

That’s incorrect. One of the youngest 4.2 engines I have seen was built mid 2007, and had plastic impellers as used from the 1st 4.2 engines build.
