O2 sensor question???
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).
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.
