Failed within a week
After I installed these, my engine light went off and all was good for about 20 miles. Then, both sensors failed within a week and sent engine codes. I had to replace them with a different brand, which worked fine, and the engine light went off and stayed off...so far. I will update when I get more miles on the truck. I'm outside the return window, so I have to eat the cost of faulty sensors. Bummer!

Perfect Fit
Perfect fit for my 2003 Chevy Avalanche and my 2005 Chevy Tahoe 5.3 L V8 upstream and Downstream sensors.Easy to install. Engine running great now with no misfiring. Great Price!! For the pair cost 75% less than auto parts store . I bought two of the two pack and replaced all 4 on my vehicle.
