For all of you that have LT Headers, CAI's do you still have you cars serviced by a Ford Dealership? If so do they give you any crap about the aftermarket parts that you have on your car? Thanks for the info.
There only going to give you crap if something breaks and you try for a warranty repair. They'll take your money for oil changes and service all day long with a smile. And don't think for a minute they don't make a note of aftermarket parts at those service visits.
