We are happy to release our N54/N55(N55 Limited Fitment) vacuum/boost adapter. This simply takes our existing external PCV fitting we use for our Catch can kits. These go inline to the throttle body and provide a full boost/vacuum signal from the manifold. For this fitting we simply remove the -8 fitting, adding instead two 1/8NPT bungs to accept any fitting that has 1/8 NPT threads. You can choose options, 1/4 barb, as well as 1/8NPT plugs if you only want one barb, etc. These are perfect for running your PI off manifold pressure which is much more accurate than charge pipe, and they are also great for BOV running the proper size line without having to drill a hole in your manifold. These do space out any sensors etc giving inaccurate readings like some of the other brands do.

They are made from 6061-T6 anodized black, with steel plugs, and Blue Anodized barbed fittings.

You can choose to order in a few ways.

• Adapter alone
• Basic kit 1 Adapter, 1 barb, and one plug, one vacuum cap, one zip tie
• Dual Barb kit 1 Adapter, 2 barbs, one vacuum cap, one zip tie
