HFS (R Automotive Oxygen Sensor Socket Set 7PC Socket Set

Overall, shipping and packaging was excellent. Unfortunately, although this tool states its 22mm, its far from it and would ultimately do more harm than good. Of the three, the closest measures at 22.3mm which would be tolerable, but the inner diameter is limited at 21.5mm which completely defeats its usage and prevents the socket from completely accepting the sensor. The set looks nice, is soooopa cheap, but utterly useless. See pics for more detail. Brand new sensor measurements included as comparison. Avoid!

Does what it is suppose to do. Took the O2 sensor out of my rusty exhaust quicker than a guy jumping out the window of a married lady’s house

Nice inexpensive kit to have around for sensors and sending units that are only replaced occasionally and don’t justify purchasing expensive tools.I replaced an O2 sensor with ease using this tool instead of fighting it with a regular deep socket or open end wrench.

Bought this socket set to remove and replace the Bank 1 and Bank 2 O2 Sensors on a 2002 Highlander that were still original. Hearing stories that sensors this old would be difficult to remove, I was fearing the worst. I did soak them with penetrating oil overnight and these sockets worked perfectly to remove them and install the new ones without a great deal of effort. And having several different ones to choose from to get into tight spots was really helpful. These sockets are pretty sturdy and have a decent case to keep them stored away in for the next time I will need them. Glad I purchased and would recommend if anybody is need of an O2 Sensor Socket Set.

I didn't know which style socket would work the best. It was actually the one I didn't think would be the best...so this kit will take care of any O2 sensor you'll ever have to change. Smart money.

I checked around for the tools to take my O2 sensors off my 2005 Chevy Silverado 1500 pick up and I like the price that I got the set of 3. The price was very good for the set. They are very sturdy and easy to use. My truck has over 350,000 miles on it and if I didn’t have them I wouldn’t have been able to get the sensors off.

Works well. Changing that O2 sensor really sucked. This tool made it possible.

This was the perfect tool to change out the O2 sensors in 2 of my vehicles. I would not have completed the job without them. Thank you.

Very poor tolerance on these sockets, almost 1mm out. Caused the socket to slip on the sensor and round off the edges. Now I am faced with a very expensive repair bill to fix it

This is a good selection for getting at those awkwardly placed O2 sensors. Between them you should find something that works on your car.

Correct delivery I am satisfied

Really a good product!

I tried two different socket sensors. Both have sloppy play and in my picture you can see they started to round off the sensor bolt head. So the quality or the fit of the sensor socket set is not very good. I do not recommend these ones. i had to cut the wires, then use regular deep socket
