2.0 Air/Fuel Ratio Gauge Lean-Rich Silver

The EQUUS 2.0 Air/Fuel Ratio Gauge Lean-Rich Silver (Model E8366) is a precision diagnostic instrument designed for engine tuning and performance optimization. This digital air-fuel ratio gauge delivers real-time AFR data, enabling technicians and performance enthusiasts to monitor combustion efficiency during dyno testing, fuel system diagnostics, and engine calibration work.

The gauge features a silver faceplate with LED illumination for clear visibility across varied lighting conditions, making it essential equipment for maximizing horsepower while maintaining fuel economy. The lean-rich display format allows users to instantly identify whether the engine is running rich (excess fuel) or lean (excess air), which is critical for carburetor tuning, fuel injector calibration, and emissions compliance testing.

This tool is intended for engine builders, performance shops, automotive technicians, and experienced enthusiasts undertaking engine diagnostics. The digital readout eliminates interpretation errors common with analog needle gauges, and the kit format includes all necessary wiring and sensors for installation into most carbureted or fuel-injected engines.
