Auto Meter Cobalt Air/Fuel Ratio 2-1/16.

Auto Meter Lunar gauges' glowing line of competition instruments feature a bright white dial face, black increments and a silver bezel. When the sun does down, Lunar comes up with a futuristic green glow created by a thin layer of phosphor that's exposed to a mild electric charge. The lighting is wired through the OEM switch and light intensity is controlled in the same way the stock dash lighting would be. Lunar will turn any custom interior into mission control! Works with most OEM and aftermarket oxygen sensors.
