12V 52mm 7-Color Car Gauge Set | Universal Multi-Function Gauge for Boost, Temperature, Pressure, and Voltage

Monitor your engine's vital signs with a single, compact 52mm gauge. This multi-function unit combines a voltmeter, boost gauge, tachometer, oil pressure gauge, oil temperature gauge, water temperature gauge, EGT gauge, and air-fuel ratio gauge into one customizable display. It is designed for universal fitment on 12V gasoline vehicles with 4, 6, or 8 cylinders.

This gauge uses a high-performance stepper motor for precise needle movement and a clear LED backlight that you can switch between 7 different colors. The button on the lens lets you change the color to match your dashboard style or personal preference. It is a professional tool for keeping an eye on your car's performance.

The package includes everything you need to install and monitor multiple engine parameters. The gauge runs on 12V DC power (10-15V range) and draws a maximum of 0.3A on the IGN line and 0.3A on the ILM line. The thread size for the temperature sensors and oil pressure sensor is 1/8 NPT. An English installation manual is included.

Key Features and Benefits

- High-performance stepper motor that delivers accurate and smooth needle movement for reliable readings.

• 7-color LED backlight that you can switch with a button on the lens, letting you match the gauge to your interior lighting.

• Multi-function design that combines a voltmeter, boost gauge, tachometer, oil pressure, oil temp, water temp, EGT, and air-fuel ratio gauge in one unit, saving dashboard space.

• Universal fitment for 12V gasoline cars with 4, 6, or 8 cylinders, making it a versatile upgrade for many vehicles.

• Professional 12V DC power range (10-15V) with low current draw (IGN MAX 0.3A, ILM 0.3A), ensuring it integrates safely with your car's electrical system.

Who Is This For

- Car enthusiasts who want to monitor multiple engine parameters without installing several separate gauges.

• DIY mechanics and tuners who need a reliable, color-customizable gauge for performance tuning and diagnostics.

• Owners of 12V gasoline vehicles with 4, 6, or 8 cylinders who want a professional-grade monitoring solution.

• Anyone looking to upgrade their dashboard with a modern, multi-color backlit gauge that matches their interior style.

Usage Scenario

Mark had just finished a turbo upgrade on his 4-cylinder coupe and needed a way to keep track of boost, oil temperature, and air-fuel ratio. Instead of buying three separate gauges, he found this 52mm multi-function unit. He mounted it in a single pod on his A-pillar, connected the sensors using the included 1/8 NPT threads, and powered it from his fuse box. Now, with a quick glance, he can see his boost pressure in PSI, check if his oil is up to temp, and monitor his air-fuel ratio during hard pulls. The 7-color backlight lets him switch from red to blue depending on his mood, and the stepper motor keeps the needle steady even when he hits boost.

Micro Comparison

Instead of buying multiple individual gauges that clutter your dashboard and require separate wiring, this single 52mm unit consolidates up to nine functions into one clean display. The 7-color LED backlight gives you customization that many single-purpose gauges lack. While some basic gauges use simple moving coils, this one includes a high-performance stepper motor for more precise and reliable readings.
