2" 52mm Car Turbo Gauge Set | Boost Water Temp Oil Pressure Tachometer Voltmeter

Monitor your engine's vital signs with this complete 52mm car gauge set. It includes a turbo boost gauge, water temperature gauge, oil temperature gauge, oil pressure gauge, tachometer, voltmeter, vacuum gauge, air-fuel ratio gauge, and exhaust temperature gauge. This kit gives you a full picture of your vehicle's performance in one package.

These gauges are designed for 12V gasoline vehicles and fit a standard 52mm / 2-inch pod or mounting hole. The tachometer works with 1 to 8-cylinder engines. Each gauge uses a clear analog display with a backlit face for easy reading, day or night.

The boost gauge comes in two versions. The PSI unit includes a turbo function, while the Bar unit works without a turbo. Water temperature, oil temperature, and oil pressure gauges come with the needed sensors. The air-fuel ratio gauge works with narrow band oxygen sensors and requires a separate sensor purchase. English installation instructions are included.

This gauge set is a practical upgrade for anyone who wants to keep an eye on engine health. It helps you spot potential problems early, from overheating to low oil pressure, so you can take action before serious damage occurs.

Key Features and Benefits

- Complete gauge set that covers boost, temperature, pressure, voltage, RPM, vacuum, air-fuel ratio, and exhaust temperature for comprehensive engine monitoring

• Standard 52mm / 2-inch size that fits most universal gauge pods, pillars, and dash mounts for easy installation

• Tachometer compatible with 1 to 8-cylinder gasoline engines for broad vehicle fitment

• Water temperature, oil temperature, and oil pressure gauges include sensors to simplify setup

• Boost gauge with dual unit options (PSI with turbo function, Bar without turbo) to match your engine setup

• English installation guide included for straightforward wiring and mounting

Who Is This For

- Car enthusiasts who want a complete engine monitoring system for a 12V gasoline vehicle

• DIY mechanics installing aftermarket gauges in a custom gauge pod or dash mount

• Drivers of turbocharged or naturally aspirated cars who need both boost and vacuum readings

• Anyone replacing old or broken factory gauges with a unified aftermarket set

Usage Scenario

Mark had just finished a turbo upgrade on his project car. He needed to keep a close watch on boost pressure, oil temperature, and water temperature during tuning sessions. After mounting this gauge set in a 52mm pod on his A-pillar, he could see his boost spool in real time and watch the oil temp climb during hard pulls. The tachometer helped him set his shift points, and the voltmeter gave him peace of mind that his charging system was keeping up. Within a few drives, he had dialed in his tune with confidence, knowing he could catch any issue before it became a costly problem.

Micro Comparison

Single gauges can be expensive and time-consuming to install one by one. This set gives you nine essential readings in one package, saving you money and wiring effort. The included sensors for water temperature, oil temperature, and oil pressure reduce the need for extra purchases. If you are building a custom dash or upgrading a daily driver, this kit provides a complete solution without hunting down each gauge separately.
