Your cart is empty.An ACDelco GM Original Equipment Oxygen (O2) Sensor is a GM-recommended replacement for your vehicle’s original component, and is a special feedback sensor on your vehicle’s exhaust system. This sensor measures the proportion of oxygen in the exhaust gases. Using this measurement, the engine management computer can adjust the air/fuel ratio near the optimum value of 14.7:1. At this ratio, engine performance, emissions, and fuel economy are all optimized. This original equipment oxygen sensor has been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

Love OEM products. Just like the factory installed. CEL light cleared. Functions just like the factory ones and noticeable change in idle. If you have installation tool you'll replace in minutes. Just plug and play.

Amazon needs to update their ACDelco compatibility catalog. This is the part number ACDelco recommends for my 2013 Chevy Silverado with the 5.3L. Exact OEM replacement. No issues. Great product for a great value through the Warehouse.

I used this to replace my O2 sensor on a 2013 Yukon 5.3l passenger side (up stream) exhaust sensor. Exact fit.

First of all, I know this is a Denso O2 sensor inside an ACDelco. This kinda freaked me out a little at first so I went to the local Chevy dealership and asked them about it. They said all their replacement O2 sensors are exactly like this. Apparently, Denso has been providing OE parts for ACDelco.I installed it and engine light went away. I hooked up the live data reader and the sensor works great.Giving it a 5 star because I only paid $38 for this whereas the Chevy dealership wanted $120 for it.Also, I know that Amazon says this doesn't fit 2008 Silverado. I can say with absolute certainty that this part does fit 2008 Chevy Silverado 6.0L 1500 V8. How do I get Amazon to change this?

These definitely are not AC Delco brand and just like the other ones that I ordered from here, I was in a pinch and there was no other ones available and so I got these but they are not what they said they were. They came in the AC Delco box just like other comments here, but they are obviously Denso and they are the cheap brand of Denso or they are incompatible because I had misfires and this was what was causing it. $100 that was wasted because they will not work on all vehicles and it really depends on which oxygen sensor they decide to stuff in the Box to give you. This is past the return When do obviously and when you add the other Downstream sensors that I bought from here that we're supposed to be ACDelco, that's $200 wasted. Amazon now has regular Denso brand that are actually cheaper but not too cheap and they work fine. Do not buy these if you have a GM vehicle

Check your connector. Ir said it was compatible. I had to cut the plug off the old one and wire it to the new part

Many of the reviews here complain that this is a Denso O2 sensor in an AC Delco box. I also saw complaints that the sensor wasn't wrapped in plastic inside the box and that the anti seize compound was not applied very well. I went to my local Chev dealer and looked at the same AC Delco part they were selling. It was a Denso sensor in an AC Delco box with no plastic wrap around the sensor and anti seize compound smeared around messily. Dealer parts rep told me that Denso and other manufacturers make their OE equivalent replacement parts.Dealer wanted CAD $128. Ordered the part from Amazon for ~ $66. Yup came in an AC Delco box and was a Denso branded sensor. Just put 2,000 kms on my 2013 Suburban after replacing. P015D code hasn't returned. Previously I had bought an NTK replacement sensor from Napa Canada and installed that but started to get all sorts of wonky codes. Apparently these sensors have tight tolerances on this GM vehicle. Bottom line is part fixed my issue. No more CEL so far.

Other cheap sensors made code appear so fitted this and they went away. Don’t go cheap on a GM especially for o2 sensors
