I noticed that this vacuum hose seems sort of flat and not very rigid (c'mon...grow up) . It is an '89 S2, as some of you will know. The car runs fine, but I just thought I'd replace it anyway as it looks like the throttle cable rubs the bottom of it. My questions is, what to I ask for when I call Zims???

Thanks.

I believe it is some type of 'breather hose' (Perhaps intake manifold breather hose?)

It is molded but very soft rubber. If I pinch it off, it effects the idle so there is definately a vacuum on it.

I was told before that it is an "EGR Outlet", don't know more, sorry

I believe that hose connects to the idle speed adjuster that sits under the intake manifold. It is a fairly pliable hose even when new. Unless it is cracked and causing issues with engine performance, just leave it alone.
