Air / Fuel Ratio Gauges

GlowShift’s Red Digital Air / Fuel Ratio Gauges are essential when tuning any performance vehicle and allow you to closely monitor your vehicle’s air to fuel ratio. This gives you multiple benefits including reduced emissions, higher fuel economy and maximized power and engine performance by allowing you to carefully map out your vehicle’s air to fuel ratios throughout the range of RPM and manifold pressure which results in maximized power output. Our Red Digital Wideband Air / Fuel Ratio Gauge features an easy to read display that determines if you are running a lean, optimal or rich mixture and reads from 10.0 to 20.0 AFR down to one decimal place by utilizing a Bosch 4.9 Wideband Oxygen Sensor that is installed to your vehicle’s exhaust with the weld in bung, as well as 13 foot sensor wire with modular connections. The Red Digital Narrowband Air / Fuel Ratio Gauge monitors your engine’s air to fuel mixture with the color coded wire harness for an easy installation and boasts a red LED digital display for quick glance gauge readings with a tinted lens housed in a sleek and ultra-thin design. A calibration start up sequence is performed every time the digital gauge is powered on to ensure proper connections and accurate gauge readings. Each Air to Fuel Ratio Gauge comes standard with all sensors, wiring harnesses, mounting hardware and instructions, as well as a one year limited warranty and free lifetime technical support.
