Turbosmart's Electric Boost Gauge is explicitly designed for turbo diesel vehicles. Unlike Turbosmart's mechanical boost gauge, which also measures vacuum, the electric boost gauge only measures boost from 4 bar.
Since diesel engines do not produce vacuum, the Boost Only gauge gives you more accurate boost readings for your turbo diesel vehicle.

Includes mount, anti-glare screen, MAP sensor , a wiring harness and a PVC pipe.

Front diameter (gauge and bezel) - 57 mm
Rear diameter (gauge body) - 52 mm
