It&#39;s common for heater codes on the front o2&#39;s with long tubes. Due to being further downstream and lesser heat retention of the headers. The applications for rear vette 02&#39;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&#39;s are the ones for our headers....how about a part number....

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.
