I have been shopping for a replacement O2 sensor and was just wondering what the difference is between one costing $150.00+ and the ones that are in the $50-$75 range.
I know I can get a no-name generic one for even less than $50 but given a choice I will go with a name brand.
I believe Bosch has a very good reputation and I have seen direct replacement Boschs in the 75-200 range but have the exact same description. Other than $150 what is the difference?
What gives?

FYI: Have you tried taking the wire wheel to that thing and knocking off all the crap? Cost me $0 and 15 minutes. It's lasted 3 more years so far...

i dont think i would try a wire wheel that will potentially damage it and will only clean the outside which you can do with a rag. the secondary sensor is wide band thats why its so expensive

wideband on 04-05 models, not the 01-03's. Still cost me $200 and change at the stealership for 2 new O2 sensors for my 02.

There is no way that carbon buildup was gonna come off with just a rag. That's why I took the wire wheel to it. Like I said, I did it in August '07 and it's worked fine since then.

thr o2 sensors a very sensitive im just saying its a bad idea.

Yes, I agree, they are sensitive. But if his sensors are already bad what is it gonna hurt? Why pay all that money when you can do this for FREE? If it doesn't work then he still has bad sensors and isn't out anything except 10 minutes or so of work.

yes i agree i just didn't want some newbi trying that because they were getting bad gas mileage or something.
