2" 52MM Digital LED Gauge Set | PSI Boost Vacuum Water Temp Oil Temp Oil Press Voltmeter Air/Fuel Ratio EGT RPM Tachometer

Monitor your engine's vital signs with a complete set of 52mm digital LED gauges. This system tracks boost pressure, vacuum, water temperature, oil temperature, oil pressure, voltage, air/fuel ratio, exhaust gas temperature, and engine RPM. Designed for 12V gasoline racing cars, it gives you the real-time data you need to keep your engine running at its peak.

Each gauge features a smoked lens and a bright digital LED backlight for clear readings in any lighting condition. The 52mm size is a standard fit for most gauge pods and panels, making installation straightforward. Whether you are tuning for performance or monitoring engine health, this gauge set delivers accurate information at a glance.

The tachometer supports 4, 6, and 8-cylinder engines and reads up to 9,999 RPM. The boost gauge measures from -15 to 45 PSI, while the vacuum gauge reads from -1 to 0 BAR. Water and oil temperature gauges range from 20 to 150 degrees Celsius. Oil pressure is measured from 0 to 120 PSI, and the voltmeter covers 8 to 18 volts. The air/fuel ratio gauge spans from 20:1 to 10:1, and the exhaust temperature gauge reads from 0 to 130 x 10 degrees Celsius.

Built with a durable plastic housing, each gauge is designed for front placement on your vehicle. The package includes the gauge, necessary sensors, cables, and a manual to help you get started. This is a practical solution for drivers who want to keep a close eye on engine performance without overcomplicating their setup.

Key Features and Benefits

- Digital LED backlight with smoked lens that provides clear visibility in bright sunlight or low light conditions

• 52mm standard gauge size that fits most universal gauge pods and mounting panels

• Multiple gauge functions in one set that let you monitor boost, vacuum, temperature, pressure, voltage, air/fuel ratio, and RPM

• Tachometer compatible with 4, 6, and 8-cylinder engines that gives accurate RPM readings up to 9,999

• Complete package with sensors and cables that simplifies installation and wiring

Who Is This For

- Performance car owners who want to track engine vitals during track days or spirited driving

• DIY mechanics and tuners who need accurate data for tuning air/fuel mixtures and boost levels

• Racing enthusiasts building or upgrading a 12V gasoline race car with a complete gauge setup

• Drivers replacing old or broken gauges with a modern digital LED set that matches a smoked lens aesthetic

Usage Scenario

Mark just finished installing a turbo kit on his project car. He needed a reliable way to monitor boost pressure, oil temperature, and air/fuel ratio to avoid detonation. After mounting this gauge set in his dash panel, he took the car for a test drive. The digital LED display made it easy to see his boost hitting 12 PSI while keeping an eye on oil temp staying within a safe range. Now he can tune with confidence, knowing he has real-time data for every critical system.

Micro Comparison

Unlike basic single-function gauges that require separate pods and wiring for each reading, this set combines multiple measurements in a unified 52mm format. The digital LED backlight offers better readability than analog needles, especially at night. With sensors and cables included for most gauges, you get a more complete solution than buying individual gauges piece by piece.
