Turbosmart’s Electric Boost Only Gauge is designed specifically for turbo diesel vehicles. Unlike Turbosmart’s mechanical boost gauge which also measures vacuum, the Electric Boost Only gauge measures only boost from 0-60 PSI. 
Since diesel engines do not produce 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
