O2 sensors same

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.

O2 Sensors - 4 pc Set

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

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!

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.

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.

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

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.

One failed within 300 miles of install
Marc
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 ??

On my 2004 Chevy Silverado, 1500, 04 upstream and downstream sensors are the same. Good quality part, working well so far at a fraction of the price of dealers. Pay attention, take your time and you'll be amazed how easy it is to replace these. Always wear eye protection under the vehicles. You wouldn't believe the crud that fell off while I was changing these. Glad that it didn't hit my eyes.
really good price and quality parts for my chevy

Fixed the rough engine idle and fuel consumption issues. Make sure to put anti seize on the threads just in case. Warning the passenger front is a little bit of a pain to get out, I had to cute the cable off the old one just to get it to fully spin.

September 25, 2023
Was hesitant at first to buy non O E M parts. But after receiving the 4 piece 02 sensors kit and the 8 pc TRQ spark plugs for my 2003 Chevy avalanche, she now runs great, no p0300 codes have been thrown, no rough idle, no misfires. A great big thank you to 1A Auto. I would highly recommend these parts.

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.
