12V Car Gauge 52mm Water Temp Oil Temp Voltmeter Oil Press BAR PSI Vacuum Boost Gauge Air Fuel Ratio EGT Gauge | Digital Display

Keep a close watch on your engine's vital signs with this 52mm car gauge. It measures water temperature, oil temperature, voltage, oil pressure, vacuum, boost, air-fuel ratio, and exhaust gas temperature. This single gauge lets you monitor multiple critical parameters to help you drive with more confidence.

This gauge uses a stepper motor for precise readings. It features a clear digital display that makes it easy to see your engine's status at a glance. The gauge is designed for stable and accurate parameter display with low power consumption, so it won't drain your battery. Its plastic shell is built to resist vibration and impact, making it suitable for demanding driving conditions.

Installation is straightforward. The gauge fits most 12-volt gasoline vehicles and is designed to fit a standard 2-inch or 52mm diameter gauge pod. Please note that these meters are stepper motors and need to be powered on to return to zero. It is normal for the pointer not to return to zero when the power is off. The gauge holder is sold separately.

Key Features and Benefits

- Digital display for intuitive observation of your engine's real-time data

• Stepper motor technology for precise and stable parameter readings

• Low power consumption helps preserve your vehicle's battery life

• Anti-vibration and anti-bump design for reliable performance on rough roads

• Universal fit for most 12-volt gasoline vehicles with a 52mm gauge opening

Who Is This For

- Car enthusiasts who want to monitor their engine's health and performance

• DIY mechanics who need a reliable gauge for a custom dashboard or gauge pod

• Drivers of modified or turbocharged vehicles who need to keep an eye on boost pressure and exhaust temperature

• Anyone replacing a worn-out or inaccurate factory gauge with a more modern digital option

Usage Scenario

Mark had just finished installing a turbo kit on his project car. He needed a way to keep an eye on the new boost pressure and exhaust gas temperature to avoid damaging the engine. He chose this 52mm gauge because it could monitor multiple parameters from a single, compact unit. After a quick installation in his gauge pod, he took the car for a test drive. The digital display was easy to read even in direct sunlight, and the precise readings gave him the confidence to push the car a little harder, knowing he could spot any potential issues immediately.

Micro Comparison

Many single-function gauges only monitor one parameter, forcing you to buy and install multiple units. This gauge combines several critical readings into one 52mm housing, saving space and simplifying your wiring. It offers a digital display for clearer readings than many traditional analog gauges, and its stepper motor provides accurate, reliable data you can trust.

Questions and Answers

Question: Will this gauge work in a diesel engine?

Answer: This gauge is designed for 12-volt gasoline vehicles. It may not be compatible with all diesel engines.

Question: Does the gauge come with a wiring harness?

Answer: The package includes the gauge and the corresponding sensor. You will need to provide your own wiring for installation.

Question: What is the diameter of the gauge?

Answer: The gauge has a diameter of 52 mm, which is a standard 2-inch gauge size.

Question: Why does the needle not return to zero when the car is off?

Answer: This gauge uses a stepper motor. It needs to be powered on to return to zero. It is normal for the pointer to stay in its last position when the power is off.

Question: Can I use this gauge to replace my factory oil pressure gauge?

Answer: Yes, this gauge can be used to replace a factory oil pressure gauge if it fits a 52mm opening and operates on 12V. You will need to install the included sensor.
