If you drive a diesel truck, especially for towing or hauling, you know that keeping an eye on exhaust gas temperatures (EGT) is crucial. Running too hot can lead to melted pistons, cracked heads, and expensive engine failure. An EGT gauge gives you real-time insight into your engine’s health, letting you back off the throttle before damage occurs.
This guide reviews the top 10 EGT gauges on the market, from budget-friendly digital options to feature-packed multi-gauge kits. We’ll break down each product’s key features, pros, and cons to help you choose the right one for your vehicle and driving style.

Buyer’s Guide: What to Consider
Choosing the right EGT gauge involves balancing features, price, and your vehicle’s needs. Here are five key factors to consider before making your purchase.
- Temperature Range: Consider the maximum EGT your engine can reach. Stock diesel trucks typically stay under 1500°F, but modified engines can exceed 2000°F. Choose a gauge with a range that gives you a safety margin above your expected temps.
- Display Type: Analog gauges offer a quick-glance needle, while digital displays provide precise numerical readings. Some models combine both. Think about your personal preference and how quickly you need to read the gauge while driving.
- Color Options: Many gauges offer multiple backlight colors to match your dashboard or personal style. If you want to match factory lighting, look for gauges with several solid color modes. Cycle modes can add a custom flair but may be distracting.
- Installation Complexity: Check what's included in the kit. Most EGT gauges come with the probe, wiring harness, and mounting hardware. Some require additional sensors or adapters. If you're a DIYer, look for kits that include everything you need for a straightforward install.
- Additional Features: Some gauges offer programmable alarms, peak memory, or self-calibration. These can be valuable for monitoring extreme conditions or for tuning. Decide which extra features are worth the extra cost for your specific use case.
Conclusion
Monitoring your exhaust gas temperature is essential for protecting your engine, especially if you tow, haul, or drive a modified vehicle. The gauges in this list offer a range of options, from simple analog units to advanced digital displays with multiple functions.
For most diesel truck owners, the GlowShift Black 7 Color 1500F is a reliable, budget-friendly choice. If you need a higher temperature range or extra features like alarms, consider the GlowShift Tinted 2400F or the JJCOCO 1800F. For comprehensive monitoring, the GlowShift 3-Gauge Set is an excellent value. Whichever you choose, you’ll gain peace of mind knowing you can keep an eye on your engine’s health.
