This flange makes it possible to add a proven power making plenum to what ever you are building. Use the blank plate and cut your own ports for what ever spacing your Intake manifold has. For VW/Audi Builds check out the Skunk DIY kits before purchasing just this flange.

The B/D series and K series side feed plenums, along with the center feed plenum will mount to this flange.

NOTE: Plenum not included!!!!!!
