GlowShift Black 7 Color EGT Gauge Kit

The GlowShift 7 Color EGT gauge is designed to monitor diesel exhaust temperatures from 0 to 1500°F. It uses a 2-1/16″ (52mm) diameter gauge with a black dial, illuminated red needle, and a clear lens. Seven solid color modes plus two color cycling options let you match interior lighting. The dimmer wire can reduce brightness by about 30% when the headlights are on, helping to preserve night driving visibility. This kit includes a Type K EGT probe and wiring for a straightforward installation. It is ideal for users seeking a compact, aesthetically flexible gauge that clearly shows exhaust temps and triggers alerts when needed.
1800°F Pyrometer EGT Gauge Kit

This EGT gauge kit provides proactive engine protection with programmable high-temperature alarms, flashing displays, audible buzzers, and a red needle warning when critical temperatures are reached. It includes a complete installation kit with a 90° bend sensor, mounting hardware, and a wiring harness for a simple, tool-free setup. The large red LED display offers clear, real-time EGT readings, while a sweeping analog needle helps drivers gauge temperature trends at a glance. A peak recall feature enhances monitoring during operation, making it a practical choice for users who want robust alerting and easy installation.
MOTOR METER EVO Series Digital Gauge Set

The EVO Series from MOTOR METER RACING provides a digital 6-gauge package with multiple display modes and switchable LED colors. It includes a GPS speedometer, tachometer, and additional gauges for fuel level, water temperature, oil pressure, and voltage. The tachometer reads signals from the ECU, suitable for 1- to 9-cylinder engines, while the other gauges deliver 2-1/16″ (52mm) measurements. This kit is built for drivers who want an all-in-one instrument cluster with clear, programmable digital displays and robust data readouts in a single install.
Ultra Thin EGT Gauge Kit with Sensor

This kit focuses on compact form without sacrificing clarity. It features a 2-1/16″ gauge with a red LED display and a high-contrast interface for at-a-glance readings. It supports peak memory and threshold warnings, and uses a programmable interface with two buttons for peak recall and memory management. The center LED readout and sweeping LED needle provide real-time temperature information, while the sensor is designed for reliability across varied driving conditions, including harsh environments common in diesel applications.
Exhaust Gas Temperature Kit 1832 ℉

The 1832 ℉ EGT kit from JJCOCO Store is professionally calibrated for precise EGT measurements across a broad range. It uses a Type K probe with a 1/8″ NPT sensor thread for a secure, leak-proof installation. The sun-friendly LED display supports real-time monitoring and customizable warnings for overheating. The kit is suitable for cars, trucks, ATVs, and marine systems, offering a robust option for those who require accuracy and reliability in demanding environments. Its universal compatibility makes it a versatile choice for diesel performance tuning and diagnostics.
Buying Guide: Key Considerations for Diesel EGT Gauges
- Temperature range and precision: Look for gauges that cover a broad range (0–1800°F or higher) with high accuracy to prevent engine damage and enable precise tuning.
- Display clarity: LED or digital displays should be easy to read at a glance, especially under varying lighting conditions. Consider peak recall and programmable alarms for proactive alerts.
- Sensor type and installation: Type K probes are common for accuracy and durability. Ensure the sensor thread size (1/8″ NPT) and installation angle fit your exhaust system and mounting space.
- Power and wiring: Choose kits designed for 12V systems with straightforward wiring. Some kits include dimming options to reduce glare at night.
- Form factor: 2-1/16″ gauges fit most dash openings; ultra-thin gauges save space in tight cockpits or custom pods.
- Multi-gauge options: If you want more than one metric (speed, temperature, voltage, etc.), EVO-style sets provide integrated instrumentation in a single bundle.
- Installation environment: Consider water resistance and housing durability for off-road, marine, or heavy-duty use in harsh climates.
- Compatibility: Confirm ECU signal compatibility and sensor calibration with your vehicle’s engine management system to avoid readings drift.
