52mm 12V Car Gauge Set | Turbo Boost Oil Temp Water Temp Tachometer

Monitor your engine's most important vitals with this complete 52mm 12V car gauge set. It includes a tachometer, turbo boost gauge, oil temperature gauge, water temperature gauge, oil pressure gauge, exhaust temperature gauge, vacuum gauge, voltmeter, and air-fuel ratio gauge. This kit gives you everything you need to keep a close watch on your vehicle's performance and health.

Each gauge features a clear, easy-to-read display with a 52mm dial face that fits standard gauge pods and mounting kits. The set works with 12V gasoline vehicles and includes sensors for water temperature, oil temperature, oil pressure, and exhaust temperature. The boost gauge offers readings in both PSI and Bar units, while the tachometer supports engines with 1 to 8 cylinders. The package includes English installation instructions to help you get everything set up correctly.

Stay informed about your engine's condition at a glance. The water temperature gauge and oil temperature gauge both measure from 40 to 140 degrees Celsius. The oil pressure gauge reads in both PSI and Bar, and the exhaust temperature gauge covers a range of 300 to 1300 degrees Celsius. The voltmeter monitors your electrical system between 8 and 18 volts, and the air-fuel ratio gauge displays readings from 10:1 to 20:1. This set helps you catch potential issues before they become serious problems.

Built with a combination of plastic and metal, these gauges are designed for durability on the road. The 52mm size is a common universal fit for many aftermarket gauge pods and dash kits. Whether you are building a custom dashboard or upgrading your factory gauges, this set provides a comprehensive monitoring solution for your car or truck.

Usage Scenario

Mark had just finished installing a turbo kit on his daily driver. He knew he needed to keep an eye on boost pressure and engine temperatures to avoid damage. He installed this gauge set in a three-pod A-pillar mount. Now he can see his boost level, water temperature, and oil pressure at a glance. On a recent highway pull, he noticed the water temp climbing higher than normal. He pulled over, found a slow coolant leak, and fixed it before it could cause any engine damage. The gauges gave him the warning he needed.

Micro Comparison

Unlike single-function gauges that require buying each unit separately, this set gives you nine different gauges in one package. It includes the sensors you need for temperature and pressure readings, so you do not have to source them separately. This all-in-one approach saves you time and ensures compatibility across the whole system.

Questions and Answers

Question: Will this gauge set work on a diesel engine?

Answer: This set is designed for 12V gasoline vehicles. It is not recommended for diesel engines.

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

Answer: No, the air-fuel ratio gauge does not include a sensor. You need to purchase one separately. It works with narrow band oxygen sensors only.

Question: What size mounting hole do I need for these gauges?

Answer: These gauges have a 52mm / 2.0 inch diameter. You need a mounting hole that fits a standard 52mm gauge.

Question: Can I use the boost gauge with a turbocharged engine?

Answer: Yes. The PSI version of the boost gauge has turbo functionality. The Bar version does not include turbo function.

Question: Do the temperature sensors come with the gauges?

Answer: Yes. The water temperature gauge, oil temperature gauge, and exhaust temperature gauge each include their own sensor. The oil pressure gauge also includes a sensor.
