The de-facto standard MDP adapter from Road Race Engineering. These guys have been in DSMs at least as long if not longer than we have (15+ years) and they always seem to have some cool, unique stuff you can't find anywhere else. This little adapter is a good example of that.

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 or add a new one part# MD632057.
