🚗 8milelake 3/8" Drive by 7/8" Offset Oxygen Sensor Socket: Efficient Solution for Oxygen Sensor Removal Review

This key was used to remove a 2003 Honda CR-V oxygen sensor and install a new one. Went like clockwork. The error code is gone and passed my test.

The socket was too small. Could have been 1/2 inch lower as I had to use a hammer to hit it on the oxygen sensor and break the wire. Not good if you want to reuse the oxygen sensor.

This is a connector suitable for very short thin wire oxygen sensors. The reason for this is that the gap width is too small for the larger oxygen sensor cable and too short for thick cable to reach the hexagon. I couldn't use it on my 2006 Infiniti QX56.

Very well made, but the side slit is not wide enough and not deep enough. I can't use it. For many applications this can be the ideal tool. My BMW 2012 750i (F01) doesn't even come close. About an inch. This is partly because the slot isn't wide enough to let the wider wire base through.

Sturdy construction, problem is I wish it was about 1/2 inch longer and the slot was a few millimeters wider. The back of the O2 sensor took up the entire length of the tube. I had to force it on and bend the wire a bit. Still, it worked and fitted well in a small space. I would probably look for another option, albeit with the above characteristics.

Can be used without removing the heat shield, saving time. Works for Toyota V6 engines, likely to fit most O2 sensor replacement parts. And much cheaper than others. When removing O2 sensors, use penetrating oil or WD-40 to aid in removing the old sensor, then apply an anti-seize compound to the new sensor to prevent corrosive seizure. Powerful enough for repeated use.

Great product, it wasn't too cheap nor too expensive, maybe a dollar or two more than I would like to pay for it. It did the job and was able to use it - took about 3-5 minutes to remove the upstream O2. I will probably use this tool again in 6 months or a year to make another O2 sensor. If you are cheap and don't want to use this tool, see if the upstream key is your alternative choice. I bought it and made my life a lot easier by removing and installing the O2 sensor. Very easy.
