Great Sensor at a great price
My check engine light kept coming on, and after hooking my truck up to my code reader, I found that I had a bad O2 sensor. Went onto Advance Auto Parts' website and found them easily. These are quality O2 sensors at a great price. They are easy to install(once you get the old one off, I heat them up with a small butane torch to make them easier to remove), and they work just as well as the OE O2 sensors. After using an online code, the price was so low, I decided to go ahead and replace all four of them. My Dodge Ram 1500 has 150,000, and factory O2 sensors are rated for 100,000. But if you don't replace them all, at least replace them in pairs.

Would not connect!
This is supposedly the exact replacement for the downstream O2 sensor on my 2001 Ram 1500 4X4. The connector looks like the old one aside from the ridges not lining up. I was unable to install this. Very irritating!
