• 20 LED Display — Twenty bright LEDs show real-time engine data that is quick to read at a glance.
• Smoke-Tinted Lens — The smoke-tinted lens looks subtle during the day and gives a clear, bright readout at night.

What It Is / How It Works

This 52mm digital gauge set is a multi-function engine gauge. It brings several engine readings into one compact display on the dashboard, so you do not need to fit a separate gauge for each reading.

Who It's For / Use Cases

It suits car enthusiasts who want to monitor several engine readings from one gauge. DIY mechanics looking for a straightforward dashboard upgrade will find it a practical fit, and drivers of turbocharged or modified vehicles who need to keep an eye on boost and air-fuel ratios are a good match.

How to Use / Care

1. Fit the 52mm gauge into an empty slot in your dash.
2. Use your existing sensor for the air/fuel ratio reading, or purchase one separately.
3. Check that the mounting hardware and English manual are in the box before you start.
4. Read the display by day or at night; the smoke-tinted lens and bright LEDs are built for both.

How to Choose

Choose by the readings you need most. The gauge reads one parameter at a time from the functions listed, so match the function to the engine data you want to watch. Compare the measurement range in the specifications against the readings you expect before you buy.
