There have been parts in Amazon that are counterfeit, I received one last October was touted to be an AC Delco, I received it 3 weeks later in an envelope from China. I purchased a correct one from RockAuto, I got it in 3 days here in Canada.
What’s the trouble with the discount code, copy and paste it in the how did you hear about us!

ok cancelled amazon, ordered thru rock with code! ended up being almost $2 cheaper. but delivery date is 6/29 now. and the worst part is itll probably come from 5 miles north of me yet has to go to their facility in secaucus,nj then back here again. ive noticed this a few times with rock. they wont even let me go there and pick it up! even if i still pay freight, ve offered a couple of times.

but cant everyone including GM get counterfeit goods as well? sometimes they are actually the same anyway.

 

The ACDelco O2 sensors are rebranded NGK/NTK.
I would insist on the Genuine GM t-stat ACD 131-158/GM 12622410. Very expensive, but worth it. If it costs much less than $30 it is not the correct one. MSRP is $60.38.
Just because a vendor is located in China does not mean fake, anymore than "made in USA" means it is not crap.

I compared the $12 EVAP purge valve from AZ to the GM $30 one. The casting marks on the plastic were identical except for the date code.

 

the total cost was about $38 for tax & shipping from rock. but man anti freeze has really increased!! $20 for a container of orange dexcool from advance.

i am still waiting for the part to show up. im thinking that i should do the hoses. after all it has about 97k and is 14yrs old and the possibility of a leak. making me think.
