Pros & Cons
Pros
Amazon sells the 02 socket aries 70039. Used four sensors on my new catalytic converters; both pre and post converter application. Perfect fit for my 05 tahoe 5.
Great deal on an ac delco part. Prefect fit. Reclipped and push pin back into support bracket.
Cons
The ac delco sensor is supposed to have a female connector. Highly disappointed.
Highlights
Quality
Easy to install, resolved the issue and improved fuel economy.
Replaced o2 sensor with open heater circuit
Heater circuit on bank 1 sensor 1 stopped working.
Drove around for about 30 mins mainly on a backroad doing 55 mph with mid throttle pressure.
Price
Very good price and these fixed my multiple missfire issue i was having on my sierra.
Great deal on an ac delco part.
You can save an average of $137 on labor if you do it yourself.
Chevy dealer wanted $125 for the part alone.
Shipping
Shipped quickly and was an exact fit as described.
Got the error code for my car, and a quick search on amazon found the right part.
Shipped fast and was very inexpensive for being a factory oe part!
Packaging/appearance
It came in an ac delco box but is a denso product and has the ac delco number.
In ac delco packaging but oem for chevy is denso.
Comes on a gm box box is different that the ones at the dealer.
Competitiveness
I know denso makes a lot of things for the car industry as oem.
Those posting it's a problem don't understand that gm uses other companies to make their parts.

Just a heads up if you are replacing the bank 1 senor 1 dont mess around just pop the 4 bolts on the front drive shaft and pull it back and let it rest on the exhaust pipe
