Discover the renowned AEM Wideband O2 Air/Fuel Ratio UEGO Gauge, a vital tool for any performance enthusiast or tuner. This gauge, with its digital LED display and color-changing sweeping LED 'needle', provides real-time air/fuel ratio (AFR) readings, shifting from rich to lean, ensuring your engine operates at its peak.

Advanced Sensor Technology: At the heart of this gauge is the Bosch 4.9 LSU sensor, renowned for its rapid response and precision. This sensor outperforms the earlier 4.2 LSU model with faster light-off times and lower power consumption, while maintaining the same fuel compatibility and not requiring free-air calibration when used with AEM’s 30-4110 Wideband UEGO AFR Gauge.

Versatile and User-Friendly Design: The gauge’s 52mm housing fits most gauge pods and can be remotely mounted for flexibility. It comes with interchangeable black and silver bezels and black and white faceplates, including a black Lambda faceplate and Air/Fuel Ratio faceplates, allowing for various color combinations and customization.

Seamless Integration: All AEM digital gauges feature a 0-5v analog output, compatible with data loggers and almost any engine management system, making integration into your existing setup a breeze.

Safety and Performance: The AEM Wideband O2 AFR UEGO Gauge is not just about optimizing power; it’s about safety. Accurate air/fuel ratio data is crucial for preventing engine damage. Running too rich can lead to power loss, while too lean a mixture can cause severe engine harm. This gauge alerts you to even minor changes in the air/fuel ratio, allowing timely adjustments to prevent damage.

Key Features:

• Bosch 4.9 LSU wideband sensor included, with weld-in bung.
• No need for free-air sensor calibration, ever.
• 52mm gauge housing suitable for a variety of installations.
• 0-5v analog output for broad compatibility (10-20 AFR range only).

With its precision, ease of use, and adaptability, the AEM Wideband O2 Air/Fuel Ratio UEGO Gauge is an essential addition for anyone serious about engine performance and safety.
