12V 52mm Car Gauge Set | Water Temp Oil Temp Voltmeter Oil Press Vacuum Boost Air Fuel Ratio EGT

Keep your engine running at its best with this complete set of 52mm car gauges. Designed for 12V vehicles, this kit includes everything you need to monitor water temperature, oil temperature, oil pressure, boost and vacuum levels, voltage, air-fuel ratio, and exhaust gas temperature. Each gauge comes with the necessary sensor for accurate, real-time data.

This multi-gauge set helps you spot potential issues before they become major problems. By tracking critical engine parameters, you can drive with more confidence and maintain your vehicle's performance. The gauges feature stepper motors that require power to return to zero, which is a normal function of the design.

Installation is straightforward with the included English instructions. The sensor thread size is 1/8ZG, making it compatible with many setups. Please note that the air-fuel ratio gauge is designed for narrow band oxygen sensors only and does not include its own sensor.

Usage Scenario

Mark had just finished installing a turbo kit on his daily driver. He knew that monitoring boost, oil temperature, and exhaust gas temperature was essential to keep the engine safe. After mounting this gauge set in his dash pod, he could see real-time readings for all key systems. On his first test drive, he noticed the oil temp rising faster than expected. He pulled over, let the engine cool, and avoided a potential overheat. The gauges gave him the confidence to push his build further.

Micro Comparison

Unlike buying individual gauges from different brands, this complete set gives you everything in one package. You get water temp, oil temp, oil pressure, boost, vacuum, voltage, air-fuel ratio, and EGT gauges with sensors included. It saves you the hassle of matching different styles and wiring setups. For a full engine monitoring solution at a reasonable price, this kit is a practical choice.

Questions and Answers

Question: Do these gauges work on a 12V car battery?

Answer: Yes, they are designed for 12V vehicles. The voltmeter measures between 8 and 18 volts.

Question: Does the air-fuel ratio gauge come with a sensor?

Answer: No, the air-fuel ratio gauge does not include a sensor. It is designed to work with narrow band oxygen sensors only.

Question: What is the thread size on the sensors?

Answer: The sensor thread size is 1/8ZG.

Question: The needle does not point to zero when the car is off. Is this normal?

Answer: Yes, that is normal. These gauges use stepper motors and need to be powered on to return to zero.

Question: Are installation instructions included?

Answer: Yes, the package includes an English installation instruction to help with setup.
