Review on 🔧 Enhance Efficiency with Powerbuilt 648691 Oxygen Sensor Offset Puller by Dave Russell

This is a very useful tool for removing and installing the O2 sensor when working in tight spaces. I bought it to remove/install the bottom O2 sensor on a Mazda RX-8 04. Honestly, I could probably just use a 22mm wrench. I didn't use the original cat's sensor, so I didn't use it to remove it. I installed the new one on the new cat before installing it on the car so I had enough room for a box/end wrench. However, I still recommend buying it if you don't have a 22mm wrench as this tool is cheaper than buying a good single 22mm wrench.
