OEMTOOLS33625246 7/8" (22MM) O2 Sensor Wrench, Oxygen Sensor Wrench for Ford 4.6 and 5.4 Engines, Swivel Head Socket, Chrome Vanadium Steel, Posi-Grip for High Torque

Good product. I was able to open the downstream oxygen sensor from the top of the engine. Works well with hyundai sonata 22mm sensor size.

Absolutely a life saver my bank 1 sensor 1 is located above the drive shaft hard to get tools into the location after 5 min with this tool got the sensor off and replaced!!! Absolutely a wonderful tool

I had a hell of a time removing a factory o2 sensor on a 2010 Challenger RT, it was cranked insanely tight so by the time I actually got the sensor off, it was totally mangled, bent, warped, threads were crushed flat. So of course not realizing how much damage I did, I tried to put a new o2 sensor in and didn't have much luck, I knew it was loose and wasn't threading properly because I damaged the internal threads on the catalytic converter. I did a little research and opted to buy this product. I removed the o2 sensor that I had installed, which was now wrecked because I tried to force it in to the damaged threads. Needless to say, I was pretty worried about having to try and replace the cat, plus some exhaust piping etc., this project was about to get expensive! I made sure the thread tapper was starting to thread properly, first tried with it attached to a rachet, but because of how tight the workspace was, I had to instead use a 7/8 wrench, which this product fits as well thankfully. It took some very serious elbow grease, but managed to thread it all the way in, loosening it back out was much easier so I knew it was having some effect. Anyway, along with a second new o2 sensor (which was my mistake on wrecking the first one), it worked like a charm. The product did have some wear, but considering how destroyed the internal threads were, it held up extremely well for the price. I would definitely buy it again or recommend to anyone else.

Crazy how a simple little bend in the handle makes this so versatile. Helped get into a wheel well to replace my 02 sensor with ease.

I purchased this product for one reason, the extended depth of the socket portion. This was added to my tools as a more specialty O2 socket as I have a few others. I reduced my rating by one star simply because there is no OEMTools branding on the socket as is seen in the picture. This has no impact on its use, but it does make any sort of support or warranty claims hard as you are required to remember who made it. It is clearly a rebranded socket, just without the added branding except the packaging.Aside from that, the socket works great. It has a solid grip on the sensor and allows you to get to sensors that are buried behind a heat shroud that prevents the normal depth sockets from reaching it. If you choose this socket over a no brand socket for the warranty and service from OEMTools, be prepared to retain your proof of purchase as the tool is not branded.

It was difficult to use this, it’s better to get a O2 sensor wrench that you can lock clockwise and counter clockwise. I had to turn it a little and remove and turn and remove.

It worked well for my mechanic and I gave it to him after they change my O2 sensors.

I had to grind about 1/16" off OD for Gen 2 Prius upstream sensor/ heat shield. It was still strong enough to break loose 16 year old sensor using 16"L X 1/2" drive flex ratchethead breakerbar. If one does not have means to do some cylindrical grinding, consider a more expense, made to fit socket. It would be nice if they told OD (~1-5/16") in the specs.I rated it 5 because of its remaining strength, figuring that I may have to grind.
