42 Draft Designs Vaccum Manifold Boost Tap are designed specifically for VW & Audi vehicles. Built on the same design as the 42 Draft Designs boost gauge tap, the vacuum manifold tap allows for the connection of a much larger vacuum line. This vacuum line can feed a larger boost/vacuum accessory - diverter valve, wastegate, or a vacuum manifold. Using a vacuum manifold and this tap, a motor which previously had no available boost/vacuum ports can now have 4!
The 42DD vacuum manifold tap fits both FSI and TSI motors. Installation is quick and reversible. No tools are required and our fitting leaves no marks on the intake manifold or PCV tube.
