Bests & Worsts Reviews from Amazon

Works well with a small $2 modification. When you attempt to remove the stubborn O2 sensor, you need a lot of torque. The slot in this socket that allows for the wire of the sensor is a weak point on the socket. You will apply pressure and it will "skip" around the bolt as the slot opens wider. Physics. A simple $2 metal hose clamp will fix this. Place the socket on the bolt. Slide the hose clamp over the wire and over the socket as close to the bottom as you can. Tighten the clamp and torque away! Once the sensor is out, loosen and remove the hose clamp. For tightening the new sensor you won't need the clamp.
