I was wondering if they served any other purpose than to shut off the SES light when you have a off-road pipe. If that is all they do, I will hold off on them, but if they are crutial to the air/fuel or something like that then I better get them. What do you think???

 

They aren't critical, they'll just keep the SES light from coming on. Your car will run fine.

 

Thanks, that is what I thought, but I just wanted to make sure....
