DelphiOxygen Sensor - ES20013

Paired this Upstream Delphi sensor with a BOSCH Downstream sensor on my '04 Escalade 5 months ago on Bank 1. It's finally time to replace the Bank 2 OEM sensors. Torquing your Sensors to OEM Factory specs will go a long way with these sensors! The best on the Amazon market.

So I ordered these without looking at my plug type first, and just went by me engine type, I was wrong. However, when I received these 02 sensors they looked great and well built. It's a shame I couldn't use them, but seller made it easy to return. Thank you

good product. arrived in a timely manner.

I had bought a cheap $20 sensor for bank 2 down stream to replace an original 02 sensor after a steady fault code. The cheap replacement eliminated the fault code for a month or so and the code would come back. This went on for about a year on my 04 Silverado 5.3 with 200,000 miles. I recently bought this Delco 02 part that was triple the money, but no more 02 fault code. The truck even seems to be performing better. Lesson learned, stay away from the cheap Amazon parts, go with a name brand.

Sensor will not register any voltage. Dead on Arrival. Removed this one and popped my current/old sensor back in and voltage reads are consistent. Better off with the old for now as this one appears to be defective. Off to find another as too late to return. Ordered and fell ill, just now had time to install. Unfortunately, I am out of luck on this one. Oxygen Sensor - GM (12583804).

So far so good no problems fit my 2010 Cadillac Escalade

Installed this product in my Escalade, it preforms well. I had to change out a cheaper version when my check engine light came back on after about 40 miles. But not with this Delphi product it is performing and the engine sound beautiful, like a drum rhythm! Get it over a cheaper counter version, don’t crawl underneath your vehicle twice, that’s not nice!

works as advertised replacement
