Hey I got your PM about SDI intake manifold P/N. I'm assuming you're talking about the SDI intake I had. I believe the part # for the lower aluminum portion is 038 129 711 L.
If that doesn't work, then try 038 129 713 L.
The upper plastic portion is
038 129 713 H (not that you need it, but it might be useful reference when searching ETKA).
