The R&D Yamaha SHO Multi-Pressure Port Adaptor Kit will allow quick and easy hook up of digital or manual boost gauges with the R&D Multi-port billet adaptor. The R&D Pressure Port Adaptor installs between the MAP sensor and the MAP sensor bracket as a “bolt on” part with no modifications. The adapter has two ports that allow for the operation of a vacuum/boost gauge, check plenum air temperatures, operate a surge protection valve, and operate a boost referenced fuel pressure regulator (RRFRP), or any two of these applications at the same time with one simple part. The R&D Pressure Port Adaptor Kit comes complete with longer MAP sensor mounting screws, o-ring seals, nylon cable ties, all mounting hardware and instructions.
