Gas Milage Salvaged
I had 2 failing O2 sensors in my 2000 ford explorer. I was getting lean fuel readings and poor gas mileage. I went a head and purchased these. My fuel trim readings have gone back to factory spec and my gas mileage has been greatly improved. Great purchase.

We have a few different aftermarket companies build these parts specifically for us, as our 1A Auto house brand. They are manufactured to the same OEM specifications as the original part that came with your vehicle. If you have any further questions, please dont hesitate to ask.
