im not real familiar with the 4.6 engines. im wanting to purchase a 96 gt. the guy selling it says that he replaced the intake with an 03 intake. i asked if it was a pi head swap and he said no, just the intake. is this possible? and would it do any good for the car performance wise? he said the 96 intake was leaking so he replaced it with an 03 intake. once again this is on a 96gt. i would appreciate anyones help. thanks!
