BMW RPI V3 Ram Air Induction Scoop - BMW E46 M3

About the RPI Scoops for BMW E46 M3

Free HP, Just Ask
You may not know, but your car has hidden performance potential.  You can extract some of that performance with bolt on items such as power pulleys or intakes, but making the most of what you have just got a little easier for a small investment.

The Factory Intake Sucks (sucks air, that is!)
The factory intake on a BMW pulls air from a number of sources (vacuum), but not limited to the front kidney grills, brake ducts (E46 M3) and even the hood (E9X M3).  This way, there are always a number of fresh air sources at all times.  RPi's Ram Air Induction scoops maximize this design.

At driving speed, the RPi scoops divert air into the intake box (or aftermarket intake, if being used)forcing air into the intake, pressurizing the intake system.  As the speed of the vehicle increases, it forces more and more air into the intake system, allowing for more HP.
