Prosport 52mm Air/Fuel Ratio (AFR) Gauge utilizes the latest Bosch Wideband Oxygen Sensor for an accurate reading. The AFR Gauge has the widest available range of 10.0:1 to 20.0:1 Air/Fuel ratio readings in the world. The Gauge can display either Amber or White color depending on how it is wired. When the vehicle is started, the Gauge will perform a full gauge sweep with a built-in self check to ensure the gauge reads accurate at all times. Incorporated into this Gauge is a Warning and Peak Feature. The Gauge can either be set to emit a beep or change color when a preselected variable is reached. The Peak function allows you to see the highest value on the Gauge during operation.
