      Reliable Vacuum Source. With the S550 EcoBoost being equipped with an electronically controlled turbo system from the factory, adding things such as a Boost Gauge or Blow Off Valve can prove to be a challenge. Turbosmart offers a simple solution to bring a reliable vacuum source to your Mustang. This Boost Reference Adapter (BRA) allows for the addition of two boost accessories without disrupting any OEM components. Hear your turbo with a BOV and easily monitor your boost via an aftermarket gauge with this plug and play adapter.

      Quality Construction. Using high quality, precision machined billet aluminum, this black finished Boost Reference Adapter connects to the PCV barb located behind the throttle body. Manufactured to provide a leak free experience, this BRA will bring the same dependability and responsiveness of a traditional vacuum style system to your modern day Pony.

      Plug and Play Installation. Adding new vacuum sources to your turbocharged Pony will be a breeze with the installation of this BRA. Crafted to mount between your factory MAF sensor and manifold, this plug and play Boost Reference Adapter will easily allow for the addition of a Boost Gauge or Blow Off Valve. All necessary NPT nipples, hose and hardware is included for a seamless installation.

      Application. This Black Turbosmart Boost Reference Adapter is specifically designed for use on 2015-2020 EcoBoost Mustangs.

        It works

        I got this along with my blow off valve and it works great. Easy to install. Looks better than the stock part.

        Super easy to install and great readings off it

        Picked this up for my Ecoboost mustang for a water methanol boost reference point and the readings were spot on for the snow map based kit!

        5 2016 EcoBoost - WheelmanM80

        More than acceptable, it's adequately satisfactory

        Works very well - use liquid thread sealer. I used this to connect a [center] vent-mounted mechanical boost gauge. I used fuel line tubing from the reference adapter, routed that through a grommet located behind the gas pedal mount (there's just enough room) and through the large gap below the dash to the passenger side. Once on the passenger side, I converted the fuel line to the small diameter plastic tubing provided by the gauge manufacturer using adapters I found at an autoparts store, then routed up and left of the glovebox through a small hole I drilled in the plastic venting, ultimately connecting to the gauge. Word of advice: leave enough slack in the air line and wiring to pull the gauge out in order to change the light bulb in the future.

        Must have!

        This is a must have for a mechanical boost gauge. In order to install your gauge because these Mustangs have an electrical blow off valve.

        5 2015 EcoBoost - Randall

        Best option

        This is a better option than using the one that comes with the turbosmart BOV kit.

        Bought this for my f150 2.7

        Super easy to now install my boost gauge and BOV on my f150 2.7 now! Did some research on TurboSmarts website and found out that it fits the mustang and F150 2.7 only.

        5 2015 Ecoboost - Surfer8039

        Great product

        This makes a big difference from prior location of vacuum tap. Goes on easy and the extra port for additional boost gauge is a plus. Make sure to use some Teflon tape on threads. This adapter is a great if you want to run another aftermarket blow off valve.

      1 Top Rated Question

      Will this work if im changing to an HKS BOV? or is this for turbo smart only? i notice you dont hold the HKS BOV anymore. is this due to not being reliable for mustang?

      • The Turbosmart Boost Reference Adapter will work with any direct fit bypass/blowoff valve for the ecoboost Mustang. The HKS valve was discontinued due to poor sales.
