52mm Car Gauge Set | 7-in-1 Digital Tachometer, Boost, Temp, Oil, Voltmeter

Monitor seven critical engine parameters with one compact 52mm gauge set. This digital display combines a tachometer, boost gauge, water temperature, oil temperature, oil pressure, voltmeter, and air-fuel ratio reader into a single dashboard-ready unit. It gives you real-time data to keep your engine running safely and efficiently.

Each gauge uses a bright blue LED readout with a red warning light that alerts you when a parameter goes outside the safe range. The 52mm diameter fits standard gauge pods and panels, making installation straightforward for most 12V gasoline vehicles. The ABS plastic housing with an aluminum ring provides durability without adding extra weight.

Whether you are tuning for performance or just want to keep a close eye on your engine health, this gauge set gives you the information you need at a glance. The tachometer reads up to 9999 RPM, the boost gauge measures from -14 to 29 PSI, and the temperature gauges cover 40 to 150 degrees Celsius. It is a practical upgrade for any car enthusiast who values precision and reliability.

Key Features and Benefits

- 7 gauge functions in one unit that let you monitor boost, temperature, pressure, voltage, RPM, and air-fuel ratio without buying separate gauges

• Blue LED digital display with red warning light that makes critical readings easy to see even in low light

• 52mm diameter housing that fits standard gauge pods and panels for a clean dashboard installation

• ABS plastic case with aluminum rim that resists wear and keeps the gauge lightweight

• 12V DC power compatibility that works with most gasoline car electrical systems

• Red warning point at 10V for the voltmeter that alerts you to low battery voltage

• Warning light above 100 degrees Celsius on the water temp gauge that helps prevent overheating

• Tachometer warning light above 5000 RPM that helps you avoid over-revving the engine

Who Is This For

- Car enthusiasts who want a complete engine monitoring solution in one compact gauge

• DIY mechanics installing a custom dashboard or upgrading from analog gauges to digital readouts

• Performance tuners who need real-time data on boost, air-fuel ratio, and engine temperature during tuning sessions

• Owners of 12V gasoline vehicles with 4, 6, or 8 cylinders looking for an affordable gauge upgrade

Usage Scenario

Mark just finished installing a turbo kit on his daily driver. He wanted to keep an eye on boost pressure, oil temperature, and engine RPM all at once without cluttering his dashboard with multiple separate gauges. After mounting this 52mm gauge set in his gauge pod, he took the car for a test drive. The blue LED display was easy to read even in direct sunlight, and the red warning light on the water temp gauge caught his attention when the engine started running warmer than usual during a long uphill climb. He was able to pull over and let the engine cool before any damage occurred. Now he drives with confidence knowing he has all the vital information right in front of him.

Micro Comparison

Unlike single-function gauges that require multiple pods and wiring harnesses, this 7-in-1 unit consolidates all essential readings into one display. It saves dashboard space and simplifies installation. While some digital gauge sets only show basic data, this one includes both boost and vacuum readings plus an air-fuel ratio gauge, giving you more insight into engine performance without needing extra sensors or adapters.
