Turbosmart Boost Gauge 4 Bar

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
