Hey, Mason here. I have a 2002 grey f-150 4 door lariat supercrew 5.4L v8. I am looking to build my truck to a speed demon. I know that the engine requires air to get to it. I have a K&N air filter in it. I just had some questins about air flow. In order to get the most air flow to my engine to get good acceleration, top speed, and gas milage, I was wondering what exactly i should go with. Should i put a throttle body spacer in? mabee a turbo? or a fresh air intake? cut my air box off? any advice would help me out. I plan on getting a chip for my truck so i know that air flow will be necessary. Also i know that when the engine takes in air it has to let the air out. so i need some advice on exhaust systems. I want a quiet clean sounding system. i dont want that loud poping sound or radling. I just want a clean clear sound that isnt to loud. so any advice on which system is better than others is greatly appreciated.

Thanks.

 

if you want cheap look up the "gotts mod" I would have done it but already had a K&N CIA... throttle body isn't gonna do much but give you a whistle sound.. and for exhaust mine is my fav... true dual with flowmaster 40s and rear cats removed... just my .02

 

supercharge it if your serious about being a 'speed demon'. No throttle body spacer, does not a thing to fuel injected modern engines. Run a Magnaflow cat-back system. Comes with the tame 18" body, stainless steel, calm & clean toned.

 

ok i will be sure to check these out thanks really appreciate it. Ill see what those magnaflows sound like.

thanks
