On eBay, item # 8021432865 for $26. Says for front and rear. Has anyone purchased these from this vendor or should they be purchased from oxygensensors.com?

Does ANYONE know if these are knockoffs or genuine? I know they're a lot more expensive from o2sensors.com, but if these will suffice then I'd purchase these. Has anyone used this eBay source for o2 sensors?
Thanks in advance for your replies!

Turbogs300,
The only thing about them that concerns me about them is the vendor told me that the sensor that he is selling "fits all three locations, guaranteed!!!". I checked the oxygensensors.com site and they show that the manifold sensor and the pre-cat sensor are the same, requiring a purchase of two of part 236-4624. They show the after-cat sensor as part 236-4623, apparently different than the other one. What would be the difference between the two? Thanks T!

Greg,
I worked on it yesterday, I was only able to get the 2 at the manifold changed. That last one (under the car) was a @$%^#! and I couldn't get it changed. I tried Liquid Wrench, WD-40, a breaker bar and a cheater and it wouldn't budge! But I have good news...(I just saved a bunch of $ by switching to Geico, just kidding!) the CEL went out and I'm very happy about that! I read in one of the many post here that the 2 important ones to change are the first 2 before the converter and the last one doesn't really matter. Do you think I'll have any problems if I can't get that last one changed out?

It will probably trigger the CEL soon enough. You're correct in that it's not the most important one, however if your cat fails or becomes clogged, it becomes pretty important then.
I'd say take a break from it for now, however keep soaking it with PB Blaster and maybe try heating it up with some map gas. It'll come out eventually.
