A-Premium Upstream and Downstream Heated O2 Oxygen Sensor Compatible with Chevy, GMC, Saturn, Pontiac Vehicles-Malibu Equinox Captiva Sport Terrain Solstice Aura Vue Sky G6, 2.4L, 2-PC Set, B1S1 B1S2

Good parts

Replaced old sensor that have been on the car for 120k miles, instantly started having issues. Car would randomly die or go into a limp mode. Now having to wait on replacements. Save your money!

Ran worse than before. (Upstream didn't match or work/ran worse than before and fouled out plugs. Backfire and all) (downstream might have worked)but I just replaced both with OE denso replacements... spend the money buy right product

The first photo is what I received. The second & 3 photo is what I needed. 2010 Chevy Equinox, the front 02 sensor did not work and the car would idle bad and stall. Had to unplug it to run. The right sensor in the first photo was the front o2 sensor that did not work. I have a picture to show the difference but nowhere to submit it? (From pic: Left sensors = rear Right sensors = Front) Black are the old vs the new clean. Neither exactly matched the old ones....

Connector and fitment as great but Stopped working after 8000 miles. Had to replace front 02 sensor again. I used a more expensive unit the second time. I learned my lesson buy once cry once. Not recommended

Complete waste of money. Has an element burned out and now I can't return it. I didn't realize that I only had 30 days from the order date and I didn't check it right away. I wish I would've checked it with the volt meter when it arrived. Absolute waste of money! Cheap junk!

I installed both sensors on my 2014 GMC Terrain. I did the downstream first and the code cleared and all was good. I lowered the car to the ground and decided to go ahead and do the upstream as well since I had it. The car would not run right and would lose power and died. I cleaned off the original and reinstalled and all was well. On close comparison it doesn’t look like the original at all. Not sure if I got a bad sensor or if the item was miss labeled. Either way car works with just replacing the downstream and not worth pulling the down stream off so I can return the complete package.

Did not work-car stalled and had to pay another mechanic to replace with another brand.

Did not work failed terribly car won’t run until I changed them out

Did not use them yet

Brand new but was not compatible to our equinox 2012 contrary of what was said

Do not buy. Our car started stalling immediately after the sensors were installed. We received multiple errors mainly saying there was a problem with the upstream sensor. We purchased a different brand and returned these. Once the different brand was installed our car ran smoothly and no errors.
