Just bee sure to use Genuine Porsche only for the expansion tank and AOS. Water pump can be Genuine or OEM.

Id only recommend Genuine BMW for such a part.
Pros: high quality, reliable
Vehicle:

I bought a new FEBI expansion tank without the silica bag. I just found out i shouldve used G12 evo instead and G13 is a disaster on these cars.
Cons: G13 is a disaster
Vehicle:
Volkswagen
You Should be using BMW only brand , as a Dorman brand will leave you stranded every couple years .
Pros: BMW: reliable
Cons: Dorman: unreliable, leaves stranded
Don't touch any tank that's not BMW original - nobody aftermarket can be trusted any more after Mahle went to China.
Cons: unreliable aftermarket, poor quality
Vehicle:
BMW
All the parts are present and correct, but the branding on the expansion tank and hoses gives me pause - these are system-critical components, and I wouldn't trust anything other than BMW originals.
Cons: untrustworthy expansion tank, untrustworthy hoses
Hatte letztes Jahr einen neuen Ausgleichsbehälter für meinen E36 gekauft, der einfach nicht gepasst hat. War nicht dicht zu bekommen, egal was man getan hat. Es hat jedesmal bei der Montage den O-Ring verschoben, weil der Behälter einfach nicht ordentlich gefertigt war.
Cons: nicht dicht zu bekommen
Vehicle:
BMW
