across the pond or in the U.S. you'll be hard pressed to find a D port intake with long runners other than the AAZ intake manifold or the 2 piece, SDI manifold. Thats the point I was making. The AAZ unit isn't even readily available in the U.S. There are a few around...but they are all from europe in one form or another as the non-TD AAZ didn't really make a showing in canada...nor did the SDI.
