Autometer GT Series 52mm Mechanicl 30 In Hg/20 psi Vacuum/Boost Gauge
Keeping track of the vacuum and boost on your forced induction application is critical for extracting the most power safely while keeping your engine in the powerband. AutoMeterÍs Boost/Vacuum Gauges provide the most accurate readings available, unparalleled response time and smooth needle movement. Taking advantage of AutoMeterÍs advanced circuitry, these gauges automatically calibrate on every startup to compensate for altitude, barometric pressure, and other atmospheric conditions. Includes an advanced MAP sensor and wiring harness for ease of installation. Designed for gasoline engines, a boost-only version is also available for diesel or extreme boost applications.
