O2 sensor question???

Sup people!

So I have a pretty simple/stupid question. I am having my transmission rebuilt and will be putting it back in sometime this week. However, once I do, I was told that replacing the o2 sensor would be a good idea. So, I looked around and found a variety of o2 sensors to choose from.

At Autozone, I found o2 sensors ranging from $40 (Bosch) - $500 (performance o2sensors).

My question:

1. Besides the price, what are the differences?

2. Are they worth it?

3. Do they TRULLY make a difference?

Any information would be greatly appreciated.

Thanks.

-Q

I would stick with the Bosch. In many cases they were what the factory used for the sensors and they have tended to be reliable for me. There's no way to justify some $500 sensor on the jeep, IMHO - those are aimed at hotter engines overall, and a simple sensor swap won't make that kind of difference.

Yeah, I wasn't planning on spending $500 on a sensor, I would rather put that money into something else. I was just curious as to why the difference in price is so drastic. I kinda figured the more expensive ones were geared more for some extreme engines.

Thanks!

One is an upgrade kit that you'll never need and the other is the $40 part that you should go buy.

Most likely the price difference is due to the small market volume combined with the engineering required on that expensive unit. Chances are that it was meant for corvettes and honda turbos or something.
