Worked great on hard to reach O2 sensor
Geetar ✓ Verified Purchase•July 30, 2023
My 04 Mustang has an extremely difficult to reach passenger side oxygen sensor due to transmission dipstick tube location. This wrench was the only type of wrench that would allow me to loosen it. I put the wrench under stress and it performed perfectly. I bought this one because it had better reviews than some similar, cheaper ones. And the 12 point / 6 point socket head was exactly what I needed because I had very little room to turn the wrench.
Worked great

I have half inch Drive which worked great once it was on my O2 sensor as tight as it was it snapped it right out of there. I highly recommend this as opposed to the cheaper models which tend to break or spread allowing it to skip.
What a Gem!

This is a fantastic tool for the job. I can't imagine getting the sensor out without this!
Use it once worth the money.

It will never wear out. O2 sensor hell without this clever tool.
Made my Bank 1 Sensor 2 Super Easy to replace!

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.
