We used to get these from Road Race Engineering. They always seem to have cool, unique stuff you can't find anywhere else. Unfortunately, they told us they couldn't provide us with a reliable source any more, so we decided to make our own.

Bolts into place of the factory MDP sensor on top of the stock 2G intake manifold. You can either screw in the included 1/4" x 1/8" NPT hose barb fitting and run a short vacuum hose to your boost sensor or directly connect an AEM boost sensor. In either case, use some teflon tape on the threads for a proper seal.

You must reuse your stock o-ring on this adapter.
