would the sensor be the same heat, power, ohm range, just the length of the wire being diff, i already have the o2 extender so would it matter if i bought front or rear?

use Bosch 13111 o2s, they are made for the rear of a c5 vette. i have them since i did my long tube install, they do have a higher burn temp tho.

Read it here, theres a post where it says the bosch O2 sensors actually have colder heaters.
Exact opposite reason people use them for f bodies with headers.
Just my opinion, I'd get OEM f body application sensors and premade extensions.

What is what you have, the bosch sensors or the OEM with extensions?

metalmechanic

What codes do you have?

metalmechanic

ok i have had these two different codes at two diff times and have made all these corrections in between, codes p0155, p1153,, i started out with o2 extensions and oem o2, two new ones, then i got the 13111 bosch c5 rear ,no extension, and still having the code, i dont see any fix other than getting a tune . im certain all my wiring is good and no ex leaks

I have those codes tuned out.
As soon as they come up it goes into OL
Tune them out and it should be fine, they're just codes that tell you the O2's are switching too slow, usually only at idle, and usually caused by LT's

If you didn't already, you can put P1153 in the advanced search here and get a lot of info.
