bbk throttlebody (if ur gonna do one do them both, u'll like the gains in both power and mpg emensely!)
as for intake manifold, the only one on the market i have seen is to upgrade to the 99+ sohc stock intake (i've personally worked on two cars making well over 500 rwhp still using this intake without any issues, both supercharged vehicles) thing is if you switch that you gotta get a set of 99+ heads. ill have to do some more research and ask some of my vendors what they might have, but as far as i know this is the only upgrade, and honestly unless your planning to do more mods like aftermarket cams, stroker kit, stuff like that, its not worth the money. only reason i did it is i have the car apart and the mod bug bit me damn hard.
id go with the first two and make a custom cold air intake with a k&n filter element on the end attatched directly to the mass air meter.
