Is there an O2 sensor that should be "wiped off or cleaned at any point". I have read that aftermarket CAI can leave some residue especially after cleaning and oiling. If so where is it located and how should one clean.

 

The O2 sensors are in the exhaust. They should not be messed with.

 

Two of them, actually, but neither contains any, "user servicable parts."

 

Umm.... If you have an O2 sensor in your "CAI", I think you might have a problem..... Okay, J/K...
