AEM 30-4406 52mm Digital Boost Gauge, -30 to 35 PSI

AEM's Digital Boost Display Gauges combine unsurpassed accuracy, speed and control with an easy-to-read digital LED interface that displays boost in 1 PSI increments, and a sweeping LED "needle" that lines the edge and moves as boost from 0 to up to 50 PSI. The boost gauge's digital readout will automatically increase and decrease in intensity due to the built in ambient light sensing photocell.AEM's digital boost gauges include a 0-5v analog output for use with data loggers and virtually any engine management system, such as the Infinity ECU, Series 2 EMS or AQ-1 Data Logger, making it the perfect solution for users who need to monitor and data log boost at high RPM on tuned engines. Each gauge includes interchangeable silver and black bezels and black and white faceplates to personalize the look of your gauge.

The AEM 30-4406 Digital Boost Gauge combines fast response, precise monitoring, and a clear LED interface for performance vehicles using turbocharged or supercharged engines. The center display shows boost or vacuum readings in 1 PSI increments, while the 24-light green LED sweep provides an immediate visual reference as pressure changes from -30 to 35 PSI. A built-in ambient light sensor automatically adjusts the brightness of the gauge face and digital readout for improved visibility in changing lighting conditions.

Designed for both carbureted and electronic fuel-injected vehicles, the AEM 30-4406 includes a brass pressure sensor and plug-and-play wiring harness for a straightforward installation. Its 0-5 volt analog output can connect to compatible data loggers and engine management systems, including AEM Infinity ECUs, Series 2 EMS units, and AQ-1 Data Loggers. This makes the gauge well suited for monitoring boost at high engine speeds and recording pressure data during tuning or track use.

The standard 52mm, or 2-1/16-inch, housing fits common gauge pods and mounting locations. Interchangeable black and silver bezels, along with black and white faceplates, allow the display to be matched to the vehicle interior or preferred installation style. The AEM 30-4406 provides a compact, functional solution for drivers and tuners who need accurate boost and vacuum information without relying on a traditional mechanical gauge.
