The ram air intake (rpi scoop + air intake) works by reducing the intake air velocity by increasing the cross sectional area of the intake ducting. When gas velocity goes down the dynamic pressure is reduced while the static pressure is increased. The increased static pressure in the plenum chamber(A chamber, located between the throttle body and the runners of an intake manifold, used to distribute the intake charge evenly and to enhance engine breathing.) has a positive effect on engine power, both because of the pressure itself and the increased air density this higher pressure gives.

We still need a pre-LCI 550i.
For everyone who's interested in this purchase round, it will be $100 for the RPI scoop (our cars only need one). Keep in mind that RPI normally sells the Z4 scoop for $129. This is a great deal for us v8 owners.
For those who are still interested, please updated the list with your v8 model and if it's a 550i (pre or LCI model),

- aznunknownx
- DRANGED - pre-LCI 550i
- navin
- Khooger
