I recently called a aftermarket perts dist. to order a tb spacer for my 97 f150.When I told him what i was going to put it on he told me that he had had some complaints about not being able to shut the hood after it was installed has anyone put one on with a stock hood (no hood scoop) and had this problem or is this guy just dumb to the fact.Also if anyone has what kind of performance have you seen from it.
