52mm 7 Color LED Car Gauge Set | Dual Display Boost Water Temp Oil Pressure Voltmeter EGT Tachometer

Keep your engine running at its best with this multi-function 52mm car gauge set. It gives you seven key readings on a single, easy-to-read dual display. Switch between boost, water temperature, oil pressure, voltage, air-fuel ratio, exhaust gas temperature, and RPM with the push of a button. The 7-color LED backlight makes it simple to match your dashboard style, day or night.

This gauge works with any 12-volt gasoline vehicle that has 4, 6, or 8 cylinders. It replaces the need for multiple separate gauges, saving space and simplifying your setup. The plastic housing is lightweight and durable, designed to fit into a standard 52mm / 2-inch gauge pod or mounting hole.

Each function has its own sensor and wiring, so installation is straightforward. The bright LED display updates in real time, giving you accurate readings while you drive. Whether you are monitoring engine health or fine-tuning performance, this gauge provides the data you need at a glance.

With seven gauges in one unit, you get complete engine monitoring without cluttering your dashboard. The dual display shows two parameters simultaneously, so you can keep an eye on critical systems like water temp and oil pressure at the same time.

Key Features and Benefits

- 7-in-1 multi-gauge design that replaces multiple separate gauges, saving dashboard space and simplifying installation.

• 7-color LED backlight that lets you match your interior lighting or choose your preferred look.

• Dual display screen that shows two engine parameters at once, so you can monitor more data without scrolling.

• 52mm / 2 inch standard size that fits most gauge pods and mounting kits for easy installation.

• Real-time sensor readings that help you detect issues like overheating, low oil pressure, or voltage drops early.

• Works with 12V gasoline engines (4, 6, 8 cylinder) for broad vehicle compatibility.

Who Is This For

- Car enthusiasts who want to monitor multiple engine parameters from one compact gauge.

• DIY mechanics installing aftermarket gauges in a standard 52mm pod or dash mount.

• Drivers of turbo or performance vehicles who need boost, EGT, and air-fuel ratio data.

• Anyone replacing old or broken individual gauges with a modern, all-in-one display.

Usage Scenario

Mike noticed his engine temperature creeping up during long highway drives. He installed this multi-gauge to keep an eye on water temp and oil pressure simultaneously. Now he can see both readings on the dual display and switch to boost or voltage when needed. The 7-color backlight matches his dash lights perfectly, and he no longer worries about missing a warning sign.

Micro Comparison

Most single-function gauges only show one parameter, forcing you to buy and install multiple units. This 7-in-1 gauge combines all essential readings into one compact display. You get the same data without the extra wiring, pods, or dashboard clutter.
