ARES 70039-3/8-Inch Drive by 7/8-Inch (22mm) Offset Oxygen Sensor Socket - Wire Gate Accesses Sensor from Side, Preventing Damage to Wires

This item works for the upstream sensor, a little more difficult for the downstream sensor.

Works and fits my 02 Accord. I don’t understand why people say it doesn’t fit their 3/8 ratchet shouldn’t be wrenching

Please be aware that this is the longer (~ 2 inch) offset, 22mm (7/8") O2 sensor wrench, which may not be usable in very tight spaces.It has a rather rough surface finish, which could be considered poor finish, but I think helps prevent the tool slipping off the sensor hex.I had to purchase this wrench, because the regular short one that I had, could not be used to remove the upstream sensors in a friend's M37 Infiniti. I had to use a long ratchet extension, and it would only fit further away from the sensor.I chose it because it did not look too deep, and because it was inexpensive.The tool is well built, has the right fit on the 22 mm (7/8") sensors, and was able to safely loosen them, even when I thought it could slip off the sensor's hex.I liked that it had the vestiges of the two corners at the ends of the missing hex side, which helps keeping the tool on the sensor hex.Very pleased with the tool and the price I paid for it

So this tool does work well with 328i xdrive bmws worked on mine no issues. Great product, good shipping experience and time. Thanks

This tool worked great to remove O2 sensor from 2013 Ford Explorer with v3.5. It was the upstream bank 1 O2 sensor. This sensor is a pain to get to but the tool did it's job.I was able to save $3k compared to dealer pricing by using this tool and cleaning the O2 sensor and adding a little cleaner for the cat. I was then able to pass inspection. I may need a new cat in the future, but I have an extra year to come up with the $$$.This isn't for an average user with a P0420 code, but if you are not afraid to work on your car and willing to take a little risk, then you may also be rewarded. I'm sure the dealer will explain the risk is great, so you have to research and decide for yourself.

This tool made it easier for me to change my O2 sensors on my Ford F150. After breaking the sensor loose, it unscrewed easily but the tool allowed me to get the leverage in tight quarters.

Perfect , strong, fit inside the tighter heat shields

I purchased this tool to replace my oxygen sensor, bank 1 sensor 2. This is the sensor just after the catalytic converter on my Hyundai Santa Fe Sport. It really made removing the oxygen sensor extremely easy. Thankfully the sensor wasn't seized at all and there was no struggle removing it. I think this is a better way than going with a box end wrench and gives you the ability to use a ratchet for more leverage. It fit the factory sensor perfectly. I just had to give my ratchet a little bit of a shove and the oxygen sensor broke loose very easily. Make sure that your replacement oxygen sensor either already comes with the anti-seize compound on the threads or make sure to get yourself some high temp anti-seize compound to put on the new O2 sensor before you install. This will make any future replacement much easier. Also make sure that you don't touch the tip of your sensor at all or get any oil or anti-seizing compound on it.Fortunately my replacement sensor already came with the anti-seize compound on it. It sounds like this is pretty common. As long as your oxygen sensor is not seized, this tool is a great way to make the job easier and to save money over going to the dealer or to a shop and getting ripped off for an easy replacement job. The tool seems very solid and I can't imagine that it would break unless you had a seriously seized (welded in place) O2 sensor.
