52mm Car Gauge Set | 7 Color LCD Digital Display Tachometer Boost Water Temp Oil Temp Oil Pressure Exhaust Temp Voltmeter

Monitor your engine's vital signs with this 52mm multifunctional car gauge set. It combines a tachometer, boost gauge, water temperature gauge, oil temperature gauge, oil pressure gauge, exhaust temperature gauge, voltmeter, and air-fuel ratio gauge all in one LCD digital display. You get a complete picture of your vehicle's performance at a glance.

This gauge set is designed for 12 volt gasoline vehicles and works with 4, 6, or 8 cylinder engines. The LCD screen offers 7 selectable backlight colors, so you can match the look to your interior or personal style. Each gauge comes with the necessary sensor, except for the air-fuel ratio gauge which requires a separate purchase and is compatible only with narrow band oxygen sensors.

The sensor thread size is 1/8ZG, and an English installation instruction is included to help you get set up. The gauge housing measures 52mm in diameter with a height of 38mm, making it a standard fit for most gauge pods or dash mounts.

Whether you are tuning for performance or just keeping an eye on engine health, this gauge set gives you the data you need in a clear, customizable format.

Key Features and Benefits

- 7 color LCD backlight that you can change with a button on the gauge, so you can personalize the display to match your vehicle's interior.

• Measures and displays RPM, boost, water temp, oil temp, oil pressure, exhaust temp, voltage, and air-fuel ratio, giving you complete engine monitoring from one unit.

• 52mm standard gauge size that fits most universal gauge pods and mounting kits, making installation straightforward.

• Includes sensors for boost, water temp, oil temp, oil pressure, and exhaust temp, so you have everything you need for a full setup.

• Suitable for 4, 6, and 8 cylinder 12V gasoline vehicles, covering a wide range of cars and trucks.

Who Is This For

- Car enthusiasts who want to monitor multiple engine parameters without installing separate gauges for each reading.

• DIY mechanics and tuners who need real-time data on boost pressure, temperatures, and voltage during performance tuning or daily driving.

• Owners of 12V gasoline vehicles with 4, 6, or 8 cylinder engines looking to upgrade their dashboard with a modern digital display.

Usage Scenario

Mark had just finished installing a new turbo kit on his project car. He needed a reliable way to keep an eye on boost levels, exhaust temperature, and oil pressure all at once. After mounting this 52mm gauge in his dash, he could cycle through each reading with a quick glance. On his first test drive, he noticed the exhaust temp climbing faster than expected and backed off the throttle in time to avoid damage. The gauge gave him the confidence to push his setup further, knowing he could spot issues before they turned into problems.

Micro Comparison

Unlike single-function analog gauges that require multiple pods and wiring harnesses, this digital display combines eight key readings into one compact 52mm unit. You get a cleaner dashboard layout with less clutter, and the 7-color backlight lets you match the look to your other electronics. The included sensors for most functions also save you from buying them separately, making this a more complete solution for comprehensive engine monitoring.
