98 V6 question.

The BBK Throttle Body is for matching up ported upper and lower intakes. Not needd for stock or naturally aspirated motors.
Your goal and money spent should be on a CAI, a VAP intake spacer, and a catback or true dual exhaust. All three working together pulling air in and then exhausting it out.
Once this is accomplished with maybe some other minor bolt-ons will set you up to get your SCT tuner and Ford 3.73 or 4.10 gears depending on your transmission.
FYI: When it comes to any bolt on modification no matter what it is, people will try to tell you that its not worth it. Believe me when I say that it all adds up. I have the car to back up that statement.
Good luck with the car and have fun with it.
