Throttle body/MAF/intake mod questions

[Derek]

I have a 1998 ford explorer sport 4.0L OHV. Well I want to add more HP by adding a throttle body, mass air sensor, and intake kit. Maybe a throttle body spacer and chip, depends on how crazy i get with this. I came to you guys for help because when researching i found many different sizes for everything so i could use some help on max. sizes or recommended sizes and what brands are reliable, that would give me the most HP and also give me better mileage. Right now i only have a K&N cone filter and a flowmaster exhaust just to let you know what i'm working with.
