I know the intake is black and exhaust is grey. Does anyone know if there is a difference between the two other than that?
Running stand alone big stuff 3 so only use 1 sensor. Engine came back from machine shop with grey sensor in intake port and having some trouble. Is that a possibility?
Thank you.
