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 Blue, 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.
