I am having them made for my car out of mild steel but I can have them made out of 1/2" aluminum for you guys if there is interest. These would be welded on to the manifold and would work really well with those of you using the 350Z intake manifolds. The MAf flange would be welded to your intake pipe.Here is a picture of my steel ones.

These are 90mm opennings.



Price would be $50 for each if I place a order of 7 or more. I can get gaskets for these too. Let me know.
