FLKQC 5pcs Oxygen Sensor Socket, Automotive Oxygen Sensor Socket Set, 3/8" 1/2" Drive x 7/8" 22mm O2 Sensor Removal Tool Kit

Works perfectly

This set was great. I’ve never replaced oxygen sensors before tackling the 4 on my 2007 suburban. This set was perfect. Along with some penetrating oil (deep creep), the job was actually enjoyable. Love having the right tool when I’m stuffed in underneath my vehicle. This job was actually fun because of this set. I kept being surprised how easily these 15 year old sensors would break loose because of the crowfoot grip of these sockets. I’d recommend breaking the sensors loose with the offset sockets first. The deep socket noticeably separates when under torque, but I think given the price point that is reasonable. Also, based on the sensor orientation on my vehicle, I used all three of the sockets. It was the right mix of solutions to catch all upstream and downstream sensors on my exhaust system.

These are needed to get sensors off. The only problem is they are a little loose so for really tight sensors, they can slip and round sensor. It’s tough to avoid if lying on your back trying to get leverage to break a sensor loose. Overall worth the money but might need to get some penetrating lubricants into threads before trying to muscle them out.

Fit the sensor perfectly. It made the project easy. The seem like they are made very well. I am happy with the purchase.

Was able to take off and put on over 15 oxygen sensors no problems no scratches even though I've dropped the tools a couple of times packaging was okay but the value number one and number two I'd say the durability passed my test I wouldn't mind buying other tools from this brand I'll keep my eye out for them.

I've replaced all of my O2 sensor in my MKV GTI, and I've never bought the special tool to do the removal for the downstream sensors (the ones under the car). It wasn't until I had to replace the Upstream O2 sensor (near firewall, under hood) that I said to myself... no way I'm doing this w/o the tool. At only $15, or slightly less with coupon, and a handy case to keep everything together, AND 2 day Prime shipping by Amazon, it was a no-brainer for me, esp given the O2 sensor is $90 or more (ie - didn't want to damage it).While I often prefer to buy American or German tools when I can (I do miss Sears and the old American made Sears Craftsman)... there are few options for specialized tools like this. If you're a pro mechanic and doing a lot of these jobs, you can justify spending well over $100 for something from SnapOn or Matco, and if you live near a Harbor Freight, you can buy just one adapter for about $8... but, for around $15, shipped to you in 2 days, with an included case, I can't recommend this set enough for the at-home DIY'er.

It does work .

Great value and works perfectly
