F/I= Forced Induction, such as super and turbo chargers. Its called F/I because these systems FORCE air into the motor to produce horse power and torque.
N/A= Naturally Aspirated. Such as any car that ISN'T super or turbo charged. All motor refers to non-F/I engines.
PS: Its hard to have a "stupid" question. They're out there, but this isn't one of them.
