Wideband Air/Fuel Ratio Gauges
An Air/Fuel Ratio Gauge can be an essential tool for tuning any performance vehicle as it allows you to closely monitor your vehicle's air to fuel ratio. The air to fuel ratio is the amount of air entering the engine in relation to the fuel present in the engine. GlowShift offers 52mm Air/Fuel Ratio Gauges in wideband models that are available in a variety of gauge series.

Benefits of Installing an Air to Fuel Ratio Gauge
Monitoring the air to fuel ratio provides your vehicle with benefits such as determining the condition of your vehicle’s oxygen sensor, reducing emissions, providing higher fuel economy, and maximizing power and engine performance. An Air Fuel Gauge assists in detecting an issue with your oxygen sensor to prevent an increase in fuel consumption, pollutant emissions as well as a decrease in power. A stoichiometric AFR is achieved when you have the correct amount of air and fuel to produce a chemically complete combustion event. For gasoline engines, the stoichiometric ratio of 14.7:1 allows the catalytic converter to operate at maximum efficiency which results in reducing emissions. A lower AFR number contains less air than the 14.7:1 ratio and is therefore classified as a richer mixture. An air/fuel mixture that is leaner than the stoichiometric ratio will have a higher AFR number, which results in more air being present and can be dangerous in turbocharged vehicles. Installing an AFR gauge can also assist in maximizing 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.
Narrowband vs. Wideband
GlowShift allows you to choose from a Narrowband Air/Fuel Ratio or a Wideband Air/Fuel Ratio Gauge. A Narrowband AFR Gauge monitors the engine's air to fuel mixture to ensure it is at optimal levels by providing you with an estimate of your vehicle’s air/fuel mixture with a lean, optimal or rich reading. If the purpose of the Air/Fuel Gauge is to detect an existing or possible issue with the sensor and checking the general mixture, then a Narrowband AFR Gauge is right for you.
A Wideband AFR Gauge provides a precise numerical reading from 10.0 to 20.0 down to the decimal place of your vehicle’s air/fuel mixture. Each 2 1/16” Wideband Gauge utilizes the included LSU 4.9 wideband oxygen sensor to attain accurate readings directly from your vehicle’s exhaust manifold. This gauge also comes standard with a 0 to 5 volt digital output that allows you to connect it to virtually any data logging or engine management system. For high performance vehicles looking to really tune their engine, we recommend a Wideband AFR Gauge as a more accurate monitoring tool.
