All O2 sensors created equal?

[EagleMark]

I'd really like to know. I've not had issues with Bosch? But I usually only buy delco type stuff...

Yea, I always thought bosch was supposed to be some of the best out there. But I am seeing more and more people online downing their o2 sensors. I have been running bosh o2's on my YJ ever since I have had it. So I ordered a NTK o2 for it, thats what it came with from the factory. Also installed 2 new NTK o2's in my WJ as reccomended by people on a WJ forum I am on. Same thing, they downed bosch o2's.

Yeah but is that another internet rumor?

I think on thirdgen there is a thread about the Bosch, and there was even some data in the thread showing the response is different/worse than the Delco.

I was running a Bosch on mine for maybe 10 years and didn't seem to have a problem with it. I pulled it simply to install the heated Delco AFS-74.

i realize this is a bosch but for the price would this wideband be an option?

That's just the sensor that goes on a controller, need the controller as well.

The ac delco ASF74 is the o2 I ordered. Got a ship confirmation today, should be here tuesday.

That wideband looks identical to the ones that came with my innovate MTX-L guages I have in my cherokee and just installed into my YJ.

I am still running a bosch o2 in my YJ (been in there a year or two) I just installed my MTX-L in it last weekend and have been watching my AFR. I will kep an eye on it and see how it does, then I will swap in the brand new NTK sensor and see if it runs any different. The 4 wire o2 I have in my cherokee is actually the exact same one thats in my YJ. Its a 4 wire heated, and I could find the vehicle end connector at the junkyards in any early-mid 90's jeep. So I used one of those sensors just cause it was 4 wire, plug was easy to find, and I thought they were all the same.
