Powerbuilt Oxygen Sensor Offset Puller, Remove and Install O2 Oxygen Sensors, Wire Gate, 22mm 7/8 Inch, 6 Point - 648691

Have you ever trying taken out a O2 sensor that is stuck really good and you O2 socket is flexing because you trying to cheap out by buying a cheap Performance tool socket! Well you came to a the right place!!! These socket will not flex, they are very well design and thick wall heavy duty socket! You will not be disappointed! High-quality! Highly recommended!

This socket was just what I needed to loosen the O2 sensor. The slit allowed it to fit around the wiring, and the offset gave me just the right leverage.

Appear to be a high quality Oxygen Sensor removal socket.

Appears durable and works. Used the 1/2" socket with swivel ratchet. Seemed like there wasn't too much play or expansion while breaking the sensor loose. Edges of sensor rounded a tiny bit. Sprayed some penetrating oil prior night before removal. Got the job done and not bad for the price point

I'm glad I went with this style vs the socket style. It's clear that this is a much more versatile way of getting into tight spots. This made changing my O2 sensor a breeze. The whole process took less than 5 minutes. This tool made changing the upstream O2 sensor simple and it is the only tool that will fit for changing the downstream/aft O2 sensor. If I had purchased a socket style socket I would have still had to purchase this one for my aft sensor anyway.I'm happy I decided to change the O2 sensor at the same time as changing the plugs on this car for my 100K service. The O2 sensor is right in the way of the #6 plug so changing the O2 sensor was a no brainer. It had to be removed to get that plug wire off anyway. Most people don't realize that the O2 sensor is a wear item just like their spark plugs and don't change them out every 100K. By the way, before anyone comments on my 100K tune up, please be aware that my vehicle used Iridium spark plugs that only need changing at 100K miles. Amazon saved me a ton of money on my O2 sensor too!I had no idea that my car wasn't performing at 100% until changing the plugs, wires, and O2 sensor. It idled smooth and had tons of acceleration, so I didn't notice anything wrong. By looking at the plugs that came out with 100K miles on them you would never know it. They looked almost new (The OEM Iridium plugs are awesome). However it runs like a Singer sewing machine now, and I wish I would have done this 10K ago. It's certain in my mind that this improvement is due more to the O2 sensor replacement than the plugs.Now if I can find a tool that makes getting those plug wires off easier. My arms are a bloody mess after wrestling with the plug wires between the engine and firewall on that car. My old plug wire pliers just didn't cut it for this application.

Used this to remove two exhaust sensers , used heat and penetrating fluid first and a hose clamp to keep it from spreading apart , not sure how many times it will last , main thing it worked for me !!

Did the job and worked great good value!

The title of this product has multiple errors. When you order this Powerbuilt 648442...what you are getting is one single O2 socket that is for a 1/2" drive ratchet. The socket size is 22mm [Metric], eqivalent to 7/8" [Standard]. The product title uses the term "sockets" which led me to think that I was probably getting two sockets: one for a 1/2" drive ratchet, another for a 3/8" drive ratchet. I assumed the part about the 7/8" drive was probably a typo.I was able to remove the Ford OEM upstream O2 sensor on a 2002 Ford Focus ZX-5 (2.0L Zetec engine) using this socket. Important to mention: I did use a 4ft. hollow pipe for extra leverage over my ratchet handle. This made the job much easier.Unfortunately, I was not able to remove the Ford OEM downstream O2 sensor on this car using the same socket on a 5" ratchet extension (a must-have due to the location) and extra pipe leverage. The socket could not sustain the torque and would flex, causing it to slip, thus it began rounding the corners of the sensor hex off. I cut the sensor wires off and tried a regular 22mm deep socket, but even my deep socket was not long enough to reach the sensor hex. I opted to saw the sensor crimp in half using a bi-metal saw; I then sheared it off with large channel lock pliers.This socket works great for installing new O2 sensors, but I can't rely on it for removing old ones. FYI: I installed new Bosch 15717 (upstream) & Bosch 15719 (downstream) sensors. I took a chance, as this product seemed like a better value. -Might possibly work for someone else, but I'd strongly recommend buying a different O2 socket with more convincing reviews and an accurate description.
