AEM 52mm Boost Digital Gauge -30-35psi

AEM 52mm Digital Boost Gauge (-30 to 35 PSI) | Precision Turbo Monitoring

Monitor manifold vacuum and turbo boost with the AEM 52mm Boost Digital Gauge. Features 24 color-coded LEDs, digital readout, and a 0–5V output.

The AEM 52mm Digital Boost Display Gauge (PN 30-4406 / 30-0306 series) gives turbocharged and supercharged vehicles unmatched accuracy and instant visibility. Combining a high-contrast central digital numeric display with a sweeping 24 color-coded LED ring, this gauge lets drivers track engine manifold pressure from -30 inHg vacuum up to +35 PSI boost at a single glance.

Designed with a standard 2-1/16” (52mm) diameter outer housing, it mounts easily into most standard vehicle gauge pods or dash panels. The kit comes as a complete standalone system including a brass MAP pressure sensor, plug-and-play wiring harness, and mounting bracket. Additionally, it features an integrated 0-5V analog output to seamlessly stream real-time pressure data directly to aftermarket ECUs or standalone data loggers.

Best Uses

1. For Turbocharged & Supercharged Street Performance: Accurately monitor engine manifold pressures across vacuum and boost conditions to ensure proper operation under high loads.
2. For ECU Tuning & Data Logging: Send precise linear pressure data to aftermarket engine management systems via the built-in 0-5V analog output.
3. For Custom Dash & Gauge Pod Mounts: Fits standard 2-1/16" (52mm) openings, pillar pods, steering column pods, or radio plate mounts.

Features

1. Dual Readout Display: Displays central digital numbers alongside a sweeping 24 color-coded LED outer ring for visual monitoring.
2. Wide Pressure Range: Measures vacuum from -30 inHg to +35 PSI of boost (or -1 to 2.5 BAR in metric modes).
3. 0–5V Analog & AEMnet Outputs: Includes a 0–5V analog output wire for datalogging or feeding signals to engine management ECUs.
4. Interchangeable Faceplates & Bezels: Allows customization with reversible gauge faces (black or white) and bezels (black or silver).
5. Standard 52mm Fitment: Ultra-slim depth design with a 2-1/16" (52mm) body for universal mounting flexibility.

Benefits

1. Prevents Engine Damage: Allows immediate detection of overboost conditions, boost spikes, or vacuum leaks.
2. Instant Visual Reference: Color-changing LED sweep (green/yellow/red) delivers critical feedback without taking focus off driving.
3. Plug-and-Play Setup: Complete kit includes the brass pressure sensor, tubing, and wiring harness needed for installation.
4. Enhanced Night Driving: Auto-dimming display automatically adjusts LED brightness according to ambient cabin light levels.
5. Universal Compatibility: Works across carbureted, fuel-injected, street, or dedicated motorsport vehicle setups.
