Great product for the money!
I installed 4 of these sensors in my 2001 Ford F-150 and they are doing great. They increased my gas mileage and also the idle is much better. I bought 4 for the price I was quoted for just one at other part stores. I’m very pleased with the product.

How do i know the difference between a upstream senor and a down stream one. Do they look the same?
Neil J October 8, 2018
The difference is the length of the cord. The upstream sensors have longer cords.
B A October 8, 2018
the upstream and down stream are different lengths
N E October 8, 2018
