The metal piece you see is the result from a problem Saabs had with
hooting noises, believe it or not. Its only function is to change
the resonant frequency of the moving part of the valve so it doesn't
make obnoxious noises during its operation :-) Search for "hooting
noise" on the saab lists, you'll probably come across it. Weird, eh?
I'm going off what some other owners were saying at one of the tech
sessions; I thought someone mentioned that the construction(not sure
what part) was metal and much more durable. Maybe it was Wayne that
mentioned it to me?
