vette o2 sensors on fbod?
vette o2 sensors on fbod? hey guys my Front o2 sensors went bad after i had my cam put in. someone told me to buy rear corvete O2 and put them in the front of my car. they said because they burn higher or hotter. what made them burn out and will the vette ones last longer. is there a certain year vette i should ask for or a good brand?
The vette ones last longer for some reason. No particular year. Parts fail over time. If your car runs real rich it will burn them out, or if you have an exhaust leak and are getting fresh 02 into the exhaust it will foul them as well. Running leaded gasoline will do it also. Geez there are a lot of things that will kill the 02's

Get the Bosch, Im pretty sure they are the better ones.
I've been told they are heate/burn hotter/whatever.
With Long tubes the O2s are further away from the exhaust port, and the gases cool down more before reaching the O2. sometimes they don't read aswell or last as long. The vette ones are placed further down than the fbody, and will read better than the factory 02 that is not as hot.
Mine still has factory ones, can't justify spending 150 on o2s that are working properly for myself...

13111 is the part number.
They fixed my car, but I do not have a lot of miles on them yet. I have noticed that if I drive under 1500RPM they will throw a code. So I keep the RPM there or above to keep the heat up in the exhaust.

Bosche 13111's (vette rear o2's) have a higher wattage heater in them. Helps to make up for cooler exhaust gases caused by headers.

Inspect the original O2 sensors that were removed. If they are coated black, it is an indication that the car is running rich. This will foul them and they will not function properly. Have the car tuned and check your plug wires and plugs to make sure they are properly gapped and the wires are in good shape for the increase in horsepower (gap gets closed as horsepower goes up). Good luck.
