Turbosmart's Electric Boost, Only Gauge, is explicitly designed for turbo diesel vehicles. Unlike Turbosmart's mechanical boost gauge, which also measures vacuum, the Electric Boost Only gauge measures only boost from 4 Bar. Since diesel engines do not produce a vacuum, the Boost Only gauge gives you more accurate boost readings for your turbo diesel vehicle.
Includes bracket, anti-glare shield, MAP sensor, wiring harness, and PVC hose.
Fascia diameter (gauge and bezel) - 57mm Rear diameter (gauge body) - 52mm
