GlowShift’s 10 Color Digital Series Wideband Air/Fuel Gauge reads and displays your vehicle’s air to fuel ratio from 10.00 to 20.00 AFR down to one decimal place. These extremely accurate readings are obtained by the included Bosch LSU 4.9 Oxygen Sensor that installs to the vehicle’s exhaust using the included weld-in bung. This wideband air/fuel gauge utilizes a 12 volt wideband controller that features a 0 to 5 volt digital output, allowing you to connect it to virtually any data logging or engine management system. This wideband air/fuel ratio gauge includes everything mentioned above as well as a 10’ sensor harness, 6’ controller to gauge harness, 5’ power harness, gauge visor and mounting hardware for a complete installation.

Each 2-1/16” (52mm) 10 Color Digital Gauge features a flat gauge face with a digital numerical readout for quick glance gauge readings. The digital gauge offers 10 different color options that include blue, green, red, yellow, white, teal, purple, pink, amber and orange. After the color orange, there are 2 additional modes that include the 10 color cycle and 10 color fade mode that utilize all of the featured colors. At startup, a self-calibration mode ensures that the gauge is performing optimally. Each gauge features an ultra-thin design with a depth of 1.32” and an LED display that measures at 1.05” x 0.43”. For an easier viewing experience while driving at night, connect the orange wire to the headlight switch source to allow the gauge to dim 50% when the headlights are on. GlowShift stands behind each product by including installation instructions, a one year limited warranty and free lifetime technical support.

Note: The Wideband Oxygen Sensor includes Bosch’s 30 day manufacturer’s warranty. GlowShift does not warranty this oxygen sensor after that 30 day time frame.
