Review on 🔋 Denso 234 4668 Oxygen Sensor: Reliable Performance for Optimal Fuel Efficiency by Nolan White

Product works great! I had a Bad Bank 1 O2 Sensor in my '04 GMC Yukon that I needed to replace and this was exactly the part I needed. It was a bit of a hassle to change the neck because I was on my back under the truck and had never done it before, so I had a lot of trouble getting the old one off because I could barely raise a hand to the fork. Until I got up, I tried again the next day, this time I didn't lie lengthwise under the truck, but slid like a "T" onto the side where the truck was on top and I was on the bottom. After that I was able to comfortably grab the plug with both of my big hands, disassemble it and then immediately pull the old one out and plug in the new one with a puller and a rotatable or flexible ratchet. PS If you want to do this make sure your car is completely cold as you will need to put your hands between the gearbox and the exhaust pipe to get to the connector and wiring harness to do this.
