Great
Greta product so far. Working as it should. Great alternative instead of buying the 300 dollar one from aem for my air/fuel gauge.

Better than Bosch
Works better than Bosch, I’ve been through 6 Bosch sensors and all failed anywhere from a week to a few months. I’ve put this sensor in and had been smooth as butter.

THIS SENSOR KILLED MY AEM GAUGE
Plugged it in, worked okay read proper idling for a few minutes. AEM gauge went out, hmm odd. It blew a fuse (never happens) replaced fuse, turned it back on, it went full lean and started smoking. Unplugged the back of the gauge really quick. Double checked everything, tried to turn it on with just power wires plugged in to the back, nothing. Plugging in the sensor harness to the back gets it to “power on” but it’s pooched, just looks like the picture. What a terrible cable… RIP to my UEGO. UPDATE: does not power on at all now after sitting
