Metal impeller is better-Andy

Who even makes one with a plastic impeller? I have heard of M50s having plastic, but I've never seen anything but metal on an M30. Did they start that shit in the 90's or something?'88 528e /// '88 M5 /// '89 951 /// '98 E430 /// '02 M5Comment

Blows my mind but all of the OEM water pumps I have used over the past little while have come polycarbonate impellers.
It's not so much that they are bad as that when the bearing goes they blow up rather than dig into the case and make noise like the metal ones do.
Having said that, I prefer steel.I'm Not Right in the Head | Random Rants and other Nonsense1st Order Logic Failure: Association fallacy, this type of fallacy can be expressed as (∃x ∈ S : φ(x)) → (∀x ∈ S : φ(x)), meaning "if there exists any x in the set S so that a property φ is true for x, then for all x in S the property φ must be true".Comment

Apparently, most of them have 2 options ( plastic & metal) when you buy it online ( look at your online bmw parts seller ).
I found this local :http://shop.oreillyauto.com/ProductD...ype=54&PTSet=A
Brand: Cardone
Part number: A5583311

Thats just really odd. I have never seen a plastic option at autohausaz, bmp, bavauto, fcp groton, etc. Don't even waste your time with those, and you may be better off skipping "Orielly Auto Parts" as well.'88 528e /// '88 M5 /// '89 951 /// '98 E430 /// '02 M5Comment
