Higher Wattage O2 Sensor Part #? Can't get search to work. Tried several different times, terms, ...
At one point, I had this info. Generally, I was under the impression the vette rear O2's were higher wattage. Therefore, they were less susceptible to the switching error codes (P1133/53, etc). However, I was told today that some of the vette years had lower wattage O2 sensors in the rear location.
So, I want to ensure that I buy the higher wattage ones. Anybody know for certain the part number? Also, are there higher wattage ones with the correct connector? Some are square vs flat. Thanks.

Bosch 13111 Corvette rear O2 sensors have the highest wattage from what I understand.

Thanks for the quick response. I guess I have some older O2's lying around. I thought somebody was making connectors that converted the 4 pin flat to 4 pin square, but I guess it is not necessary.

Yep, I thought that the fronts were flat.
Can't believe what some people want to charge for the adapters.
