GlowShift’s Narrowband Air/Fuel Ratio gauges do not include a sensor. These gauges come with sensor wiring only and are designed to be installed onto an existing single wire Narrowband o2 sensor. If your vehicle does not have one from the factory one can be purchased here on our website.
GlowShift’s Wideband Air/Fuel Ratio Gauges include a 4.9 LSU Wideband o2 sensor.
