Review on 🔧 OEMTOOLS Oxygen Sensor Socket Set 27110, O2 Sensor Removal Kit, 22mm (7/8) O2 Sensor Socket, 3/8" and 1/2" Drive, 3-Piece Socket Set with Case by Kyle Omaha

Well packaged. Includes three O2 sensor ports: 1 "deep" "split" port with 3/8 actuator. I couldn't use this connector until I cut the wires from the sensor; it was (very) a bit too short 1 split crow's foot bushing (3/8" drive) 1 split crow's foot bushing (splined drive) I bought the kit to work with a badly frozen/rusted rear O2 sensor. There weren't any Problems with access but needed the right tool for the job I only used a 3/8" houndstooth head. Unfortunately, this does not move the sensor. Instead, the cut "widened" slightly, allowing the bushing to rotate, further rounding out the already badly corroded sensor. In the end, the only way to get it out was to use a large adjustable wrench. It worked well enough, but half the threads came out of the muffler with the sensor - I probably should have used heat (I couldn't start the car due to other issues). In fact, I only had problems because the sensor was completely frozen (and rusted from the start); However, I was hoping that those sockets could pull it out without resorting to an adjustable wrench. If you have a frozen sensor in a hard-to-reach spot, I'm not sure this will help.
