o2 sensors......need advice

[Methodical]

Ok. I am thinking of replacing my 02 sensors. My car is over 10 years old and after my accident the car set for over 4.5 years. Just came back to life on 5/27/05. Do you think it's necessary to replace the o2 sensors? I figure just about everything else has been replaced - why not the 02 sensors as well. Also, what affect will new o2s have on my Kamrfs (tune). I figured new 02s can help dial in my tune

What brand of o2 sensors is a better quality - I'm thinking of purchasing from Ford.

Thanks for your help.

www.oxygensensors.com $50.00 a piece shipped.

I will warn you that my car had 180k on it when I changed mine... made NO difference what so ever. LOL

I wouldn't replace them unless you really need them i.e. getting a code or idle problems.
