Review on 🔧 Lisle 12100 O2 Sensor Socket by Daniel Haddo

If you think all O2 sensors are the same size, think again. The question is not in the hexagon head, but in the depth. The hex head fits perfectly, but this socket is tapered, much like some of the socket designed for spark plugs. I'm not sure why it should be designed that way. Unfortunately, due to the narrow passage, it does not fit my truck at all. You might want to check the shape of your O2 sensors before ordering this one, or it might just sit there collecting dust like mine. Update: Since the check engine light went out again I went with the HF for a much shorter one at 2/3 the price. HF's worked great with a flex drive, a cheat bar and a little bit of my muscle power. I broke the O2 sensor with no effort. Save your money and get a much shorter one.
