Boost Gauge – Electric – 4 Bar (Boost Only)

Boost Gauge – Electric – 4 Bar (Boost Only)

Includes:
1x Boost Gauge, bracket, anti-glare shield, MAP sensor, wiring harness, and PVC hose.

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 4 Bar.
Since diesel engines do not produce vacuum, the Boost Only gauge gives you more accurate boost readings for your turbo diesel vehicle.

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