Turbosmart's Boost Reference Adaptors (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 allowing full, uninterrupted pressure to the MAP sensor. The two ports allow users to run various accessories, such as boost gauges and blow-off valves, with the responsiveness, versatility and reliability that a traditional vacuum-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.
