52mm 7 Color LED Tachometer Gauge Set | Boost, Water Temp, Oil Temp, Oil Pressure, Voltmeter, EGT, AFR

Keep a close watch on your engine's vital signs with this complete set of 52mm car gauges. It combines a tachometer, boost gauge, water temperature gauge, oil temperature gauge, oil pressure gauge, voltmeter, exhaust gas temperature (EGT) gauge, and air-fuel ratio (AFR) gauge in one coordinated package. Each gauge features a bright 7-color LED backlight and a clear dual display that shows both a traditional needle and a digital readout.

This gauge set is designed for 12-volt gasoline vehicles and works with 1 to 8-cylinder engines. The high-speed stepper motor provides a quick and accurate response to changes in engine conditions. You can easily switch the LED backlight color using the button on the lens, letting you match the gauges to your interior lighting or personal preference.

An alarm function is built into the system. If a reading goes outside the normal range, the backlight will flash red to immediately get your attention. The package includes individual sensors for the boost, water temperature, oil temperature, oil pressure, and exhaust temperature gauges. The air-fuel ratio gauge requires a separate narrow band oxygen sensor, which is not included. An English instruction manual is provided to help with installation.

Key Features and Benefits

- High-speed stepper motor that provides a quick response to engine changes for accurate real-time monitoring.

• 7-color LED backlight with a button on the lens lets you customize the look of your gauges to match your style.

Who Is This For

- Car enthusiasts who want to monitor multiple engine parameters with a matching set of professional-looking gauges.

• DIY mechanics installing a custom gauge setup in a 12-volt gasoline vehicle with a 1 to 8-cylinder engine.

• Drivers who value a visual warning system that alerts them to potential problems before they become serious.

• Owners of tuned or modified cars who need to keep a close eye on boost, temperature, and fuel mixture.

Usage Scenario

Mark had just finished a turbo upgrade on his project car and needed a reliable way to monitor the new setup. He installed this gauge set in the dashboard, running the included sensors for boost, oil temperature, and water temperature. During a test drive, he noticed the water temperature gauge climbing higher than usual on a hot day. The red flashing alarm caught his eye immediately, letting him pull over and check the cooling system before any damage was done. The clear dual display confirmed the exact temperature, and the matching 7-color backlight gave his interior a clean, race-inspired look.

Micro Comparison

Unlike buying individual gauges from different brands that may have mismatched sizes, colors, or display styles, this set provides eight gauges with a uniform 52mm diameter and a consistent 7-color LED backlight. The built-in alarm function adds a layer of safety that many basic gauges lack. This package is a practical choice for anyone who wants a complete monitoring solution without the hassle of piecing together separate components.
