52mm Blue Digital Wideband Air-Fuel Ratio Gauge Kit

The Prosport 52mm Blue Digital Wideband Kit is an essential monitoring tool for performance enthusiasts, utilizing a state-of-the-art Bosch LSU 4.9 wideband O2 sensor. This gauge provides a remarkably wide air-fuel ratio (AFR) reading range, spanning from 10.0:1 to 20.0:1, which the manufacturer claims is the widest on the planet. The display features a clear blue LCD readout at the center, complemented by a bar-graph style LED around the perimeter that visually indicates AFR status. These LEDs transition from Green for Rich mixtures, to Yellow for Optimal, and finally to Red for Lean conditions, offering immediate, at-a-glance feedback. Designed for ease of integration, this kit boasts a plug-and-play installation and comes with a 10-foot wiring harness, a weldable O2 bung, and a visor/hood. It also provides a 0-5 volt output signal, making it suitable for data logging purposes, allowing for detailed analysis of engine performance. The gauge itself is a standard 52mm (2-1/16 inch) size, fitting common gauge pods and mounting solutions. While marketed for universal applications, it is important to note that some adaptation may be required depending on your specific vehicle setup. The product is designated as Universal Applications, and buyers are advised to ensure fitment prior to purchase. This gauge is intended for use within the United States and has shipping restrictions to certain regions and countries, including California.
