Brand New Direct Fit O2 Oxygen Sensor For Chevy GMC Hummer Cadillac Pontiac OSA61319

Fast shipping and very well packaged. Installation went as expected with perfect fitment. Excellent customer service with an actual human being to assist your concerns if they arise.

TRQ has helped me save money with my own auto repairs both on my own Monte Carlo and Impala, and I trust them for my friends and family with their parts as well. This O2 sensor is the one of cheapest options I found, and you wouldn't be able to tell in the slightest.

Between me, my wife, and 3 kids we have 5 cars so I'm always fixing something. I ALWAYS buy from 1A! Service is always great and the parts ship fast and are always correct the first time. And if I'm in a jam, they have TONS of great how-to videos showing how to replace just about anything on your vehicle!

I have ordered Pat's for my vehicles twice now and both times I received quality parts Wich worked perfect . The staff was great in making sure I got the right parts the first time .they were pleasant to deal with . The shipping was fast I got the parts faster than they said I would . I will be using them from now on whenever I need parts their prices are better than anyone else local. Would definatley recommend to anyone. if you need parts call these guys first

I buy all my auto parts from 1aauto because you just can't beat their price and awesome customer service, not to mention to helpful videos.<br />You guys keep up the good work and i will keep on buying your parts.<br />Just got a set of 02 Sensors and my car is purring like a kitten.<br />I highly recommend giving these guys a chance, you won't regret it.<br />5 Stars all the way .<br />Thank you 1aauto

The O2 sensor arrived when predicted. Snipped the connector off of the sensor to be replaced. Made removal much easier. After the new O2 sensor was installed it took about 20 miles of driving for the service engine light to clear.

Easy to install. The how to video didn't match to where I had to change the part of for my 2004 Chevy Impala 3.4L, but it fit correctly. I just had to buy a special socket to install, but that was expected.

One of the O2 sensors didnt look like the picture online, but it seems to be working with my car none the less. Buying this item from A1 Auto was half the price as anywhere else!

I ordered a new downstream o2 sensor for my 2001 Silverado 1500. The site said the one I ordered would be a direct fit. After cutting the harness off of my old sensor (as instructed to do so in 1aauto how to video) I noticed the new harness will not fit into the existing port. There was an extra notch in the new bracket that wouldn't fit in the port. So now I'm driving with a completely useless o2 sensor until the new correct part arrives. Still like the site though. Heck of a lot cheaper than local auto parts stores. Just needs more clarification in the online description.

I give them one star because it was the correct sensor<br />And theyre supposed to refunded my money (still waiting)....<br />Brand new out of the box They all just didn't work!! Threw 5 codes on my truck.PAID TO HAVE THEM INSTALLED so I'm out that money. BIG INCONVENIENCE AND A LOSS FOR ME.<br />I wouldn't recommend using TRQ I'm second guessing the front cv axles I've installed on my truck from them after experiencing this.<br />There probably just wired wrong but they should've been tested before it left the production line
