We are happy to release our BMW B54/N55 (Limited N55 Fitment) vacuum/boost adapter. These go inline with the Throttle Body fitting and provide a full boost/vacuum signal from the manifold. This fitting adds 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. You can choose straight or 90-degree barbs.
Adapter alone – $40
Basic kit – 1 Adapter, 1 barb, and one plug, one vacuum cap, and one zip tie $45.00
Dual Barb kit – 1 Adapter, 2 barbs, one vacuum cap, and one zip tie $55.00
