Wideband UEGO Air/Fuel Ratio Gauge 52mm (2-1/16”) with 4.9 LSU Sensor, Digital AFR Controller Gauge, Wideband O2 Control Sensor kit | 0-5V Analog Output (10-20 AFR Range)

Been working spot on for over a year no issues. Only think I can say compared to the authentic AEM gauge is that this one responds just a little slower but is still accurate.

Funciona perfectamente

This kit comes with everything you need and works great with accurate readings. Easy to install, looks good, and even customizable. Both the wires are more than long enough for any mounting location. I have been using this gauge for the whole summer in my Boosted car and it has held up great. Also it's way cheaper than the name brands and I can't see why you wouldn't go with this.

Stopped working after a month. Now showing 14.6, at whatever RPM or boost, even when the car is off.
