all of them flow more than your motor can ever use with a few exceptions
( and this is off the top of my head from an old hot bike comparo on evos)
stock 132 CFM
hype-charger 145 CFM
no air cleaner 105 CFM, cupped hand 150 CFM
----------------------------
more than the motor can demand:
S/E ( round) 280 CFM ( K&N)
Ness 320 CFM ( K&N)
Zipper's 380 CFM
If you like the looks of the ventilator you'll get the same advantage as most other products- however some leave an ugly plug and wiring exposed on the throttle body ( 9 o'clock) on 08+ models

hi flow air cleaner and exhaust will be the most power increase for the least buck.
the ness big sucker is the value leader, about $120 from easternpc on ebay--- and that's the chrome backing plate version, not cast grey ( uses the stock cover, hides the plug)
pipes; your choice, make the right decision the first time.
