The front upstream 02 sensor heater circuit on my 04 Honda Civic 1.7 died, and I had a smog check coming up. Over the years, I've learned that removing these 02 sensors requires a "MAP gas" hand torch (yellow torch bottle, brand is Bernzomatic). These are popular in the auto repair field. The blue or green bottles used for camping contain a different type of gas, and they're not hot enough for this type of job. I used the Lisle socket tool to install the new sensor. The entire job only took about 25min.

This is a solid socket. It's a litter taller than the Tekton which is also a solid socket. I used this with RT Angle Milwaukee impact ratchet and it worked wonders. The socket held up no problem and the impact ratchet was the only way I could get enough twisting force into a tight space. Without it, I couldn't keep the socket square with the sensor when attempting by hand.

Worked great to remove my oxygen sensor. Did what it was supposed to do, needed a breaker bar and some penetrating oil...but the socket is very sturdy and reliable.

Quality Lisle tool for removing O2 sensor. I usually spray the area around the sensor with penetrating oil and let it soak. Then remove easily with this tool.

Was delivered in a timely manner. A perfect fit. Was able to use breaker bar. Did use liquid wrench 24 hours before trying to remove sensor.

If you're reading this review, undoubtedly you're in the market for a cheap O2 sensor socket. More than likely, you're like me, someone looking to DIY an o2 sensor replacement on their vehicle and reading about the need for a socket with a wire relief. In my opinion, since I was saving enough money by doing the sensor replacement myself, the tool purchase was justified and made the job much easier/quicker. This socket is well made and stout. When I bought it, it was among the cheapest I could get via amazon prime. I don't know if I would recommend it were that not the case. Good luck in your endeavours.

I purchased this to change the oxygen sensor on my 6-cylinder 2001 Jeep Wrangler. It fit on the oxygen sensors, but that is about the best thing I can say about this tool. Oxygen sensors tend to get grimed up and stuck. The slit in the side of this socket gives the socket too much flex and play, and seems to pop off when trying to exert the pressure required to loosen the sensors. It's far easier to cut the pigtails off thee old sensors (you're throwing them out anyway) and use a normal, deep socket.It does do a nice job for installing the new sensors, however. You clearly want to keep the pigtails intact, and the pressure to put the new ones in is not nearly that of trying to remove the grimy, stuck old ones.

This is a well-made, heavy socket designed to remove/install oxygen sensors on most cars. I used the socket to replace the post-catalytic converter sensor located underneath my car. This sensor was fairly easy to access and the Lisle socket worked as designed, removing the old sensor quite easily and tightening up the new one without a hitch. Unfortunately, the second sensor, located before the converter, has a heat shield around it that the socket is too thick-walled to pass through, so I will have to try and remove the heat shield before I can use this socket on the second sensor.Bottome line: This is a well made socket that works, but if your vehicle uses a heat shield around the oxygen sensor you may need to remove the shield before you can use this socket.

I've learned that changing the oxygen sensors, like many DIY activities, is more challenging than it seems. But with the right tools, it can be rather painless. On my car, a Toyota Camry, I used an open-ended wrench on the downstream sensor, but this socket was necessary to access the upstream sensor under the hood.This socket is very heavy-duty, fits snugly over the oxygen sensor, and offers the option of using a 3/8" socket wrench or an open-ended/box wrench, depending on what you find more comfortable. It is perfect for the job.Based on my experience, I strongly recommend that you get part numbers off your oxygen sensors in order to ensure you get the correct replacements. You'll need to remove the sensors to read the part numbers. I ordered my sensors ahead of time, following Amazon and other web sites' recommendations. After pulling my old sensors, I found that I had to re-order both.Back to the socket, though, it's heavy duty, fits perfectly, and just right for removing/installing oxygen sensors.

I bought this tool to replace the oxygen sensor on my 2002 Audi A4. After receiving the tool and the sensor, I realized that the Bosch sensor for Audis comes with a corrugated "armadillo" cable whose diameter is too large for the narrow slot in the side of this socket.I still rate the socket highly as it's clearly a quality product, just not for oxygen sensors with thicker cables. Try the offset type of oxygen sensor wrench ( ) for these applications, they work well.
