I have an Autometer Cobalt Air/Fuel Ratio Gauge for Sale works great $50 shipped.
This is from autometer's web site:
"Air / Fuel Ratio Gauge, 2 1/16" Digital, Auto Meter Cobalt Series 6175, Range Lean - Rich. Will work with most factory narrow-band O2 sensors. This product has no provision for dial illumination/backlighting."
Gauge has been slightly used but is still in great working condition.
What you see in the picture is what you are getting. This gauge comes in an Autometer box but it isn't the original one. There are no instructions, but they can be downloaded from Autometer's webpage.
