i recently discovered that my throttle body was not original and that it was bigger then stock and the only marking i found on it was HAD, i googled it and did not find anything on it has anyone heard of this ? HAD???
Pretty sure HAD is just the standard throttle body dude. Mine has HAD on it and is standard and the J's TB has this aswell, which is just a standard TB bored out isn't it? So could have been done by anyone really, any other markings/plates?
