Review on ABN 3/8in Drive x 7/8in (22mm) Oxygen Sensor Socket with Side Wire Cutout - Ideal for O2 Removal and Installation on Any Vehicle by Jason Arkin

The sensor on my BMW E46 was easy to remove although I had to use a breaker. Not sure if this is E46 specific, but the sensor wires were a bit tight and I didn't push the tool all the way in when installing the new sensor and damaged the wire harness. Although this is my fault, this could have been avoided if the adapter was half an inch taller, hence the 4 stars. The rest of the adapter is very solid. No problem with a purchase recommendation, just push it through carefully so that it gets stuck on the nut.
