O2 sensors same
May 13, 2019
So all the O2 sensors on the vehicle that I received are the same sensors down stream or upstream. Easy to install once you broke the old ones free and cleaned out the threads with a thread chaser (highly recommended). Came on time and was quick.
June 12, 2019
Not sure what else to say about them, they worked.
June 13, 2019
Works good got my check engine light off.
Works great on 2003 GMC Yukon XL
July 14, 2019
Got check engine error for Bank 1 sensor so decided to replace all four. No errors so far @ week 3.
Goodbye Pesky Check Engine Light
September 5, 2019
So far so good. These O2 Sersors were fairly easy to install and my check engine light has gone away.
O2 Sensors - 4 pc Set
November 3, 2019
Purchased for installation on my 2004 Chevy Avalanche. Sensors fit perfectly and wire lengths exactly as those installed. Sensors were individually boxed and sealed in plastic/mylar bags. Drove the vehicle about 20 miles and checked sensor readings with an OBD-II scanner. All readings satisfactory. Shipping was fast. Will definitely consider 1A-Auto for future purchases. Rob in CT
1a auto never disappoints
November 13, 2019
As always when Ive ordered from 1a Ive received the correct item in a timely manner. I recommend 1a to everyone I know when they are ordering parts online.
O2 Sensor set
January 15, 2020
I only ordered the part after my husband told me what my baby needed. The parts arrived just as planned. They were a perfect fit and other than having huge forearms making it difficult to reach, they were a breeze to install per my husband. We love 1AAuto!
2005 chevy O2 sensors
February 13, 2020
These were delivered promptly. The price is half what you would pay at an auto store. They worked as expected. It helped with fuel economy and check engine light is now off.
Perfect fit, right parts
March 8, 2020
My mechanic put my hubs and 02 sensors on with no problems at all. Will continue to shop here for sure
O2 Sensors - perfect fit.
May 3, 2020
The O2 sensors are a perfect fit and solved the issue. Check Engine light turned off in less than 10 cycles. Fast delivery, easy to install.

August 27, 2020
I would definitely recommend this product. Fast delivery & easy to install.
Looked and worked as good as OEM
September 20, 2020
I previously bought sensors off of Amazon to replace my oem O2 sensors and they went out after a few days. These were the same quality as oem and Ive had them on for a month with zero issues.
All (4) 02 sensors for a 2005 Tahoe
September 21, 2020
The sensors came fast. And already had anti-seize on the threads. Clear the check engine light and it has not came back on Tahoe seems to run smoother. Watch the video they provided which was great help.
4 oxygen sensors
October 19, 2020
The parts were perfect, great price, free shipping. Part that was the issue was a bad fuel pump. Returned 4 oxygen sensors and received refund. Thank you, 1A auto. Joseph Coates
O2 install
November 8, 2020
three of the four installed fine. Fourth one on upstream passenger side could not remove old one. Will have to take to the shop to see if they can remove it and install part. Seem to be running a little smoother even with just three new ones installed. Hopefully this will clear all end it is not the fuel pump.

April 13, 2021

Nothing more to say, exceptional.
June 21, 2021
I was very satisfied with my purchase. All the items fit perfect and installation was easier than I expected. Would highly recommend to anyone. Have been ordering through 1A FOR OVER 5 YEARS NOW.
One failed within 300 miles of install
August 8, 2021
One of the four oxygen sensors failed within 300 miles. Was 200 miles from home when it happened and was charged $60 for another sensor at Napa auto parts and $120 by a shop to install since I had no access to tools or a jack to install myself. That sucked.
perfect on my car and the price awesome ??
December 12, 2021
Perfect product thank you five stars
February 8, 2022
I called to ask about the warranty on my o2 sensors and prompts were easy to follow plus ill have a new sensor in about 7-10 days
March 12, 2022

Will recommend
March 30, 2022

April 3, 2022

Too good to be true? The price? Warranty? It's real. It's true. Replace those old 02 sensors today.
July 7, 2022

September 18, 2019

Does it matter up stream down stream are they all the same on 2005 chevy silverado I bought a set and they were all the same ones?
April 4, 2020
Rick S
Theyre all the same, i had one go bad, but i just changed them all out. No specific order, 05 Tahoe 5.3
April 4, 2020
In my 2003 Suburban they were exactly the same. Up stream and down stream refers to in front of the cadilletic converter and behind the cadilletic converter. The sensors perform the same job , monitoring efficiency of the converter. These signals are sent to the onboard computer.
April 4, 2020
Matthew M
it does not matter all the same
April 4, 2020
No . You can use the same oxygen sensors on bank one and on bank two.. They are all the same. Good luck! Justin
April 4, 2020
Justin R
