52mm 7 Color LED Car Gauge Set | Boost Water Temp Oil Pressure Voltmeter Air Fuel Ratio Tachometer

This 52mm car gauge set brings seven essential readings into one unified display. With a 7-color LED backlight, it gives you real-time data on boost, water temp, oil temp, oil pressure, voltage, air-fuel ratio, and RPM. Built for 12V racing cars, it helps you monitor engine health and performance at a glance.

Each gauge delivers clear, accurate information so you can drive with confidence. The 7-color backlight lets you match the look of your dashboard or choose a color that stands out in low light. Whether you are tuning for the track or keeping an eye on daily driving conditions, this set covers the key metrics that matter.

The gauges are housed in a plastic shell with a 52mm diameter, making them easy to install in standard gauge pods or custom panels. They are designed for universal fitment on 12V vehicles with 4, 6, or 8 cylinder gasoline engines. Each gauge comes with its own sensor and wiring, so you get everything needed for a complete installation.

From monitoring turbo boost pressure to checking exhaust gas temperature, this set helps you spot issues before they become problems. It is a practical upgrade for anyone who wants to keep their engine running smoothly and safely.

Usage Scenario

Mark had just finished a turbo upgrade on his 1990s sports car. He needed a way to keep an eye on boost pressure and engine temperatures during hard pulls. After installing this 7-gauge set, he could see his boost levels climb, watch water and oil temps stay safe, and check his air-fuel ratio for a proper tune. The 7-color backlight let him set a soft blue glow that matched his interior. Now he drives with full confidence, knowing his engine is running exactly where it should be.

Micro Comparison

Unlike single-function gauges that require separate mounting and wiring, this set gives you seven readings in a coordinated package. The 7-color LED backlight offers more customization than standard single-color gauges. Each gauge includes its own sensor, so you do not need to source additional parts for installation.
