AEM X-Series EGT 0-1800F Gauge

AEM X-Series EGT Gauge 0-1800°F (30-0305) | Digital Exhaust Temp Monitor

Monitor exhaust temperatures up to 1800°F (1000°C) with the AEM X-Series EGT Gauge (PN 30-0305). Features a slim 52mm design, AEMnet CAN-bus, and high-visibility digital display.

The AEM X-Series Exhaust Gas Temperature (EGT) Gauge (Part Number: 30-0305) delivers high-accuracy thermal monitoring designed for high-performance turbocharged, supercharged, and diesel engines. Reading temperatures from 0°F to 1800°F (0°C to 1000°C), this gauge allows tuners and drivers to monitor critical combustion temperatures, preventing engine damage caused by lean fuel mixtures or excessive boost.

Engineered with AEM’s advanced single-board layout, the gauge offers an ultra-slim depth of less than 0.825 inches (with a cup depth of just 0.200 inches), enabling custom installation in tight interior spaces or flush-mount gauge pods. The display features a center LED screen that is 87% larger than standard gauges, paired with a 24-green-LED sweeping needle for immediate visual feedback. With built-in AEMnet CAN-bus integration and a 0–5V analog output, the X-Series EGT gauge seamlessly feeds telemetry to standalone ECUs, engine management systems, or data loggers.

Best Uses

1. High-Boost & Turbocharged Builds: Monitoring exhaust temperatures during high-load pulls to protect pistons, valves, and turbochargers from thermal degradation.
2. Diesel Tuning & Towing: Tracking EGT spikes under heavy load, towing, or aggressive tuning to prevent head gasket failures and melted internals.
3. Dyno Tuning & Fuel Calibration: Assisting tuners in dialing in optimal air-fuel ratios and timing maps alongside a wideband UEGO sensor.
4. Data Logging & Standalone ECU Integration: Transmitting real-time EGT telemetry to engine management systems like AEM Infinity or 3rd-party loggers.

Features

1. Ultra-Slim 52mm Profile: Standard 2-1/16” (52mm) mounting size with an ultra-thin 0.825” total depth for flexible placement anywhere in the vehicle.
2. Enhanced High-Visibility Display: Center digital readout is 87% larger than previous generations, surrounded by a 24-LED green sweeping ring.
3. Dual Output Connectivity: Features both AEMnet CAN-bus and a 0–5V analog output to connect directly with data loggers and ECUs.
4. On-Face Peak/Recall & Warning Buttons: Easily view maximum recorded temperatures and configure customizable high-temp alert thresholds directly from the gauge face.
5. Reversible Scale & Auto-Dimming: Supports both Standard (°F) and Metric (°C) readouts, paired with an auto-dimming light sensor for optimal visibility in any lighting condition.

Benefits

1. Prevents Costly Engine Failures: Instantly warns you of dangerous temperature spikes caused by lean conditions or excessive timing advance before catastrophic damage occurs.
2. Effortless Pod & Custom Mounting: The ultra-shallow design eliminates clearance issues in tight dash assemblies and aftermarket pillar pods.
3. At-a-Glance Readability: The oversized display and high-contrast sweeping LEDs let drivers quickly check thermal status without taking focus off the track or road.
4. Seamless System Integration: Enables advanced engine management systems to trigger safety cuts or fuel enrichments automatically using the 0–5V/CAN-bus data feeds.
5. Versatile Compatibility: Dual °F and °C functionality allows effortless tuning across both standard and metric preferences without replacing hardware.
