Hi, want to change my maf sensor for a bigger one the one I have is stock and I think is 55mm. I read on some forms that the maf from a thunderbird will fit and that is a direct bolt on. So I went and got one dron the junk yard today. I got one dron a 97 thunderbird and I need to know if this will work with my Foxbody 93 with 19 lb injectors and if is a bolt on, I need to know if it worked fine and if I will have any problems? Is my first time posting something here so just learning. I really need your help . Thanks.
