Easier to install than it was getting the old ones out. Took two days of driving time for codes to clear. Was little worried till they cleared. Passed emission inspection.
Most Liked Negative Review
Junk in one week!
Bought this sensor as a maintenance item, car has 110000 on it. In one week I get a p1071 code. I still had the old sensor so I put it back in and code didn't come back! There's quality for you one week old versus 110000 police miles!

Worked great. Get the socket adapter!
I bought this as a replacement part for my 2006 Pontiac Montana SV6 minivan that was giving me the check engine light and a couple fault codes, the hardest part about the whole process was getting to the old one. Once I removed the old one I used the supplied thread coating and applied it to the new one, once I put a generous amount on I put in into the socket and torqued it down. After I cleared the codes I restarted the vehicle and the codes have not returned. So far this product is doing what it was desinged to do.
Bottom Line Yes, I would recommend to a friend
