vette rear 02's for our headers

[bud8fan]

It's common for heater codes on the front o2's with long tubes. Due to being further downstream and lesser heat retention of the headers. The applications for rear vette 02's have a larger/higher amp heater in them that seems to work in such cases.
is anyone here using these on your headers...if so do you know which year model vette rear o2's are the ones for our headers....how about a part number....

I do remember someone posted that up before. Its like a Bosch 18111 or something like that. It will be in the archives somewhere if not in the sticky pages for LS1 conversions.

Got some deja vu reading that.

I don&#39;t have them in the front. Even with my LT&#39;s I didn&#39;t throw codes with the stock front O2&#39;s. I did throw codes with the stock rear O2&#39;s and replaced them with the vette units. It cured the problem.

Yes I still have cats. I never have gotten codes on the fronts. As you found all 4 02&#39;s are the same. To test if it is heat related try wrapping some header tape around the header in the 02 area?
