Review on 🔧 KAX 3/8-Inch Drive, 7/8-Inch (22 mm) Offset Oxygen Sensor Socket: Easy O2 Sensor Removal & Installation, Wire Gate Access for Side Entry, Prevents Wire Damage, Fits All Vehicles by Dwayne Quarles

I wanted to replace the O2 sensor on my 35-year-old pickup. This tool worked GREAT. I ran the engine for half an hour to warm it up, sprayed copious amounts of WD40 and used a foot length pipe tool on the ratchet handle to get it to turn about 1/8th of a turn. I wiggled the sensor back and forth a few times and then sprayed more WD40. I left it on for about an hour, then put the tool back on and it came out right away. Very good quality tool.
