Has anyone used these O2 Sensors?

[MilwaukeeS4]

So I recently purchased my first S4 (2001) and I purchased it with a CEL for a bad O2 sensor. The code is P1118 which is the passenger side downstream sensor. Details say that the heater circuit is open. I've been searching for the correct replacement part, and came across these o2 sensors for a very low price.. Just wondering if anyone has any experience with them, and if would not recommend this, then if they could point me in the direction of the part they would use. I'm also curious if the upstream and downstream o2 sensors are the same? Because I've looked and seen both have the same part number... Sorry for sounding like a real idiot but I am slowly learning everything I can about this car and want to make it my project build, and want to do as much as I can myself. Thank you for any feedback or help!

Here's the link to the o2 sensor I was talking about.

Broken link. Best route to take is the bosch universals. They are like 42 bucks a pop and you do not solder. In fact, Bosch recommends not soldering. They include the solderless weatherproof connector.

Sorry, fixed the links now. I appreciate you posting a direct link to the ones on amazon, so that would work to replace any of my 4 o2 sensors? Also I was looking for one that has the connector already wired in, do I just cut the wires right before the old connector and splice this one in with the solderless connector provided?

Ok so I think I'm going to go this route with the Universal Bosch sensor. Just one more question, I watched the video that was with it showing how to install the new sensor, and it says to cut the wires of each at the same length, I'm wondering how much this matters? Also does it matter if I cut it to be a little longer than my original O2 sensor is? I'm just thinking for the future if I want to move my o2 sensor farther down, this would make it easier without having to buy another sensor.

Yes they will work. Yes u will reuse the Audi oxygen sensor wiring.

Pull the old one. Cut wires such that the length will match the oem length. There is a black, gray, and two white wires. You can connect any white to any white. Attach black to black. Gray to gray. I'd have the splice as close to the Audi connector as possible to ensure the splice won't be subject to as much heat/elements.

Are you sure those will work for all 4 it says it fits downstream which is B1 and B2 S2.

I run them in mine with no issues. Oxygen sensor is an oxygen sensor. There are others on here that run them as well. They will/can attest.

Alright, just making sure thanks

Yeah B5 S4 uses the same o2 part for all four locations.

Ordered my new O2 sensor, can't wait to get rid of this CEL so I can pass emissions and get out on the road! Thank you for your help!

I ordered 2 of those from amazon too (for my primary 02s downpipes). I have a check engine light for one of them but doing both of them.
I got them already and they look great installing tomorrow or Thursday. I'll let you know how it goes. In the future ordering 2 more for my rears to get rid of the cel.
