I have read about CAT deletes and the issues with throwing codes. I also read about O2 sensor "Eliminators, Extenders" etc, including the simple solution of using a spark plug 'anti and/or non-fouler'. Many threads talk about how quick and cheap and easy it is to use a non-fouler to help fool the computer and/or O2 sensor.... the issue I have is how in the heck does a 14mm spark plug non-fouler thread into a bung hole designed for an 18mm O2 sensor? what is the trick I am not reading about?? any help is appreciated and no, I would not normally simply delete my cats, but heck, even with a muffler delete my ZL1 exhaust is not all that loud or noticeable... thanx in advance.
