I am selling my rubber boot off my 1988 Wolfsburg GL, that goes between the
AFM and throttle body. It is still soft and has no cracks.

I bought a new one trying to track down a vacuum leak, actually it is a
whistle that happens when I just open the TB.  I have sprayed flammable
sprays around joints but no leaks were detected.  I figure that it is just
the noise the air makes flowing past the butterfly valve...
(Yes I have replaced the seals on the throttle body main shaft and it is not
loose)

$24 plus shipping.
I am near Raleigh, NC
