ok i got an ideal for one hella cool intake.
i would want it set up with 2 throttle bodies but take to much work so we are going to skip that not even sure it will work pop in my head at work.
here are the steps
#1 buy z3 fenders
#2 cut into fenderwell make airbox with concial filters in them on both z3 fender(where the slits are)
#3 run both up over the engine connecting to a single pipe running across the spark plugs having the pipe connect in a Y shape into the throttle body
problems with this
#1 z3 fender slit go the oppiste way of air force so difference scoops would be needed on the fenders so open wide mouth ones would be great
#2 if you could rig twin throttles and mafs i beleive it would work even better
#3 thats a hella expensive intake i mean you need new fenders for it
so a crazy design i wish i hade money to make would most likely work well i mean to ram air intake sucking up outside air with twin thottle and a good manifold that should rock for n/a cars
remenber this was a crazy ideal made up a work with less than 3 hours of sleep in the last 36 hours man thats when i think the best lol later
