wideband O2 sensor on rear bung, would it fit?

[nwbDSM]

I just got AEM UEGO wideband. My car doesn't have a CAT and I believe that I can just install a wideband o2 sensor in the rear o2 location. My question is, would the o2 sensor (I believe "bosch") that comes with AEM wideband kit fit perfectly in the rear o2 bung, or do I have to re-thread it?

Thank you.

It will fit. Make sure you do not have any leaks pre sensor. A small leak will throw off your sensor reading by a good bit.

Thanks for confirming. I will check for any leak before installing it.

+1 for liquid, I have mine in rear o2, had a tiny leak at o2 housing to downpipe flange and it threw my reading off drastically, if you are using link v3 you will most likely need to select AEMwideband R1 in the dropdown menu to get it to match up with the link AFRest. Hope this helps-Gary

I ran mine there for the better part of a year. I just switched it to right before the flex section on my DP. The thing that always annoyed me about having it in the stock location was how long the lag was for the reading. Its not too bad at WOT but its a noticeable lag while cruising

I have the red and black wires connected from the four prong, off the Uego. I have the WB O2 sensor plugged in before my cat. My question is: where does the white wire from the four prong connect?
