The 5 Best O2 gauges (2023 reviews)

The latest glowshift o2 gauge is an absolute beast in terms of its features, and rightfully takes the top spot with ease. The Glowshift tinted 7 color series digital wideband air/fuel ratio gauge is essential for mapping out the air to fuel ratios of your gasoline or e85 flexfuel performance vehicle. It is world renowned for providing exceptionally crafted and competitively priced automotive gauges with an extensive variety of styles and options.

There's a wiring harness for the gauge to operate but it's a stand-alone kit and doesn't need to be integrated into your existing wiring. It comes with a bung for the wide-band o2 sensor. This is a great gauge that works very well.

Best Runner up: Fhrhry O2 Gauge

Buy on Amazon

We are personally inclined towards fhrhry o2 gauge, it is not so pricy, but it overachieves its purpose and outstanding in important aspects. It’s the cheapest way to an AFR gauge. It is perfectly accurate and reliable system for a fraction of the name brand stuff. It has instructions for how to wire the gauge into the wires from the O2 plug. The Gauge works great, which is not surprising since it is a simple electronic system that only shows the output voltage from the sensor via readout/indicator lights on the gauge faceplate.

The Lambda label plate has AFR graduations and vice versa for the AFR faceplates. The 52 mm ( 2 - 1/16 inch gauge housing ensures that it fits most instrument pods and can be installed remotely almost anywhere. The 4.9 lsu sensor provides speed and accuracy for the controller, so it can react quickly even for every 0.1 air-fuel ratio change, allowing you more time to respond and protect your engine safety. It is suitable for a specific series of manufacturing equipment.
