Purchased the upstream and downstream O2 sensors as a set for my 2008 Altima. After installation, there was a noticable response in the accelerator. Also, fuel mileage increased back to original levels. Although a great product, the asking price for these 02 sensors is ridiculous. I've bought several 02 sensors in my life and these are by far the most expensive.
