Keep a close watch on your engine's vital signs with this complete set of 52mm car gauges. It combines a tachometer, boost gauge, water temperature gauge, oil temperature gauge, oil pressure gauge, voltmeter, exhaust gas temperature (EGT) gauge, and air-fuel ratio (AFR) gauge in one coordinated package. Each gauge features a bright 7-color LED backlight and a clear dual display that shows both a traditional needle and a digital readout.

This gauge set is designed for 12-volt gasoline vehicles and works with 1 to 8-cylinder engines. The high-speed stepper motor provides a quick and accurate response to changes in engine conditions. You can easily switch the LED backlight color using the button on the lens, letting you match the gauges to your interior lighting or personal preference.

An alarm function is built into the system. If a reading goes outside the normal range, the backlight will flash red to immediately get your attention. The package includes individual sensors for the boost, water temperature, oil temperature, oil pressure, and exhaust temperature gauges. The air-fuel ratio gauge requires a separate narrow band oxygen sensor, which is not included. An English instruction manual is provided to help with installation.

Why You Will Love It

Having a full set of gauges makes you feel more connected to your car. You can spot problems before they turn into expensive repairs. The clean 52mm design looks great on any dashboard, and the stepper motor movement gives you that professional feel every time you look at the needle.

Questions and Answers

Question: Does this gauge set work with diesel engines?

Answer: The tachometer is designed for gasoline 4, 6, and 8 cylinder engines. The other gauges (water temp, boost, oil temp, etc.) should work with any 12V vehicle, including diesel.

Question: Does the boost gauge include everything I need to install it?

Answer: Yes, the boost gauge comes with a nylon pressure line (2m for bar version or 1.84m for psi version) and one adaptor, plus an English manual.

Question: Can I buy just one gauge instead of the whole set?

Answer: Yes, each gauge type is sold individually. Choose the one you need from the options.

Question: How do I wire these gauges to my car?

Answer: Each gauge comes with wiring instructions in the manual. They are designed for 12V systems and typically connect to a power source, ground, and signal wire from the sensor.

Question: Will the pointer move right away when I turn on the car?

Answer: The pointer will reset to zero after power is connected. If it does not return to zero immediately, that is normal for stepper motor gauges. It will self-calibrate after power is applied.
