2″ 52mm 7-in-1 Car Gauge Set with Smoke Lens | Tachometer, Boost, Vacuum, Temp, Oil Pressure, Voltmeter for 12V Vehicles

Monitor seven critical engine functions with a single, coordinated gauge set. This 52mm (2-inch) kit includes a tachometer, boost gauge (PSI and BAR), vacuum gauge, water temperature gauge, oil temperature gauge, oil pressure gauge, and a voltmeter. The matching smoke lens and sleek housing create a professional, unified look for your dashboard or A-pillar pod.

Each gauge is designed for 12-volt gasoline vehicles and covers the most common measurement ranges for performance and daily driving. The water temperature, oil temperature, and oil pressure gauges include the necessary sensors for installation. The boost gauge, vacuum gauge, and tachometer do not require sensors, making them straightforward to wire into your existing system. An English installation manual is included to guide you through the setup process.

This set is ideal for anyone who wants to keep a close eye on their engine's health. Whether you are tuning for performance, monitoring for potential issues, or simply adding a custom look to your interior, these gauges deliver reliable readings at a glance. The smoke lens reduces glare and gives the display a modern, subtle appearance when the lights are off.

Key Features and Benefits

- Seven essential gauges in one set that let you monitor RPM, boost, vacuum, temperatures, oil pressure, and voltage from a single location

• 52mm (2-inch) diameter with smoke lens that fits standard gauge pods and reduces dashboard glare

• Includes sensors for water temperature, oil temperature, and oil pressure so you can start measuring right away

• Works with 1 to 8 cylinder 12-volt gasoline engines, making it suitable for a wide range of cars and trucks

• English installation manual included that helps simplify the wiring and sensor connection process

Who Is This For

- Car enthusiasts who want to track engine performance and catch problems early

• DIY mechanics installing a custom gauge setup in their own vehicle

• Owners of turbocharged or high-performance cars who need boost and vacuum readings

• Drivers who prefer a coordinated gauge set with a matching smoke lens look rather than mismatched individual gauges

Usage Scenario

Mark recently installed a turbo kit on his daily driver and wanted to keep an eye on boost levels and engine temperatures. He picked up this 7-in-1 gauge set and mounted the gauges in a standard 52mm A-pillar pod. After a quick wiring session with the included manual, he could see his RPM, boost pressure, water temp, oil temp, oil pressure, and voltage all at once. On his first test drive, he noticed the oil temperature climbing higher than expected during a hard pull, so he backed off and let the engine cool down. The gauges gave him the confidence to push his car harder, knowing he could spot any issues before they became expensive repairs.

Micro Comparison

Many single-function gauges require you to buy each one separately, which can lead to a mismatched look and higher total cost. This set gives you seven matching gauges with a unified smoke lens design, so your dashboard stays clean and professional. The included sensors for temperature and pressure gauges save you the hassle of sourcing them individually.

Questions and Answers

Question: Do all the gauges come with sensors?

Answer: No. The water temperature gauge, oil temperature gauge, and oil pressure gauge come with sensors. The boost gauge, vacuum gauge, tachometer, and voltmeter do not include sensors.

Question: Will these gauges work in a diesel vehicle?

Answer: These gauges are designed for 12-volt gasoline vehicles. The tachometer is suitable for 1 to 8 cylinder engines. Diesel engines have different ignition systems, so compatibility is not guaranteed.

Question: What size hole do I need to mount these gauges?

Answer: You need a 52mm (2-inch) diameter mounting hole for each gauge. Standard gauge pods and panels with 52mm openings will fit these gauges.

Question: Is the installation manual easy to follow?

Answer: Yes, an English installation manual is included. It provides wiring diagrams and instructions for each gauge. Professional installation is recommended if you are not experienced with automotive electrical work.

Question: The pointer is not at zero when I receive it. Is that normal?

Answer: Yes, this is normal. The pointer may not rest at zero when the gauge is not powered. Once you connect power, the pointer will return to the correct position and function properly.
