I am a Porsche tech who mainly works on 356s, and I recently acquired a large lot of parts from a VW, Audi, Porsche shop. I am trying to ID this part so I can sell it and get it to someone who can use it! Don't want to scrap it, might be good to ship off to get extrude honed.....I can't make out all of the part number and I have tried searching different combinations with no success. Hopefully someone can help me determine what it is. I'm not sure if the pictures are posting, please copy and paste this link, hopefully it will work.

I tried to run that part number that was cast into the manifold but it doesn't work in my VW or Audi Etka parts program. And they don't always work on an item like this either. So this will be one that somebody will have to visually ID for you. I was thinking 1.6 VW rabbit, but I could easily be wrong since it's been a long time since I've had one of those cars. I read the number to be 058-126-591-A, I tried the number with and without the A, no luck.
