My check engine light was on and I had it diagnosed at Autozone and the code came up as an upstream O2 Sensor, but they sold me a downstream sensor. My check engine light was still on after installing so I went back to Autozone. They told me I could bring it back. I was fed up with the back and forth so I went on You Tube and was educated by video and code on how to install upstream and downstream O2 sensors & saw the Ad for 1A Auto Parts and ordered all 4 upstream & downstream O2 Sensors for a little more than it cost me for one at Autozone. Yes I an very satisfied with 1A Auto Parts and will continue to buy from them with their how- to helpful videos.
Best deal ever!

I never got a code that o2 sensors were bad but I am getting terrible mpg(like 7mpg I saw this deal online that get you all 4 for just a little more than price of one at most places. After replacing I got a Check engine light that one was bad, put 1 old one back on and check engine light went away, still getting terrible gas mileage so these were not the problem but I did get a faulty one, so you get what you pay for.

Would have never tried to do something like this on my own. But the price at a shop was ridiculous. And with the 1A video showing me how to do it was a breeze. I got all 4 sensors for the price of one at the auto parts store near me. Thank you 1A
Great up stream o2 sensors

I bought the four pack o2 sensors for my 2003 Toyota Sequoia. I was not sure they would work. They are doing great for two weeks now. The sale reps are great too.
Good deal for a set of 4

Exact fit. Look to be different than OEM on the tip side but none the less worked. Connectors were good.
One came with defaults

Perfect service.

I saved hundreds of dollars with 1AAuto. They also stock and ship the exact hard as the car dealership and not a bump up "made-to-fit" item. I didn't ship my part to rush. Regular shipping was sufficient.
Excellent purchase

The o2 sensors and removal tool were just what I needed. Received them in a very timely manner and exactly what I purchased. The quality is outstanding and have always used A1Auto as my go to parts store.

It was just a good idea to replace all of the sensors at the same time. Now they are all new and It saved me money! Always a good thing. Got the sensors in a timely manor and they just worked.

50% better mpg

My truck had not thrown a code but was getting 10 mpg for the last 2 years. I read that o2 sensors can wear out but not enough for a check engine light. I replaced all 4 and the next 2 times i got upper 14's for mpg. Hopefully they last!
Poor quality sensors.

Replaced all original sensors when one needed replacement at 190k miles. One out of four A1 sensors were bad. Failed after 2 weeks of use. Cost my daughter $400 to have repaired since I could not help her remotely. Replaced bad sensor with Bosch part.
