Turbosmart's Boost Reference Adapters (BRAs) allow access to a reliable boost reference, without compromising the operation of the car's standard sensors and control systems. 

 The BRA attaches between the vehicle's MAP sensor and the intake manifold, providing a pressure source to two ports, while still allowing full, uninterrupted pressure to the MAP sensor. The two ports allow users to run a wide variety of accessories such as boost gauges and blow-off valves, with the responsiveness, versatility and reliability that a traditional manifold pressure-operated system offers.

Precision-machined out of billet aluminium, Turbosmart's BRAs ensure an excellent fit, zero leaks and complete compatibility with the OEM MAP sensor.
