if air flow is almost doubled, eiher the engine runs lean, or the power is doubled!
Seriously, what that statement means?

That is information from aFe. Simply put the filter itself is capable of flowing a good bit more air than the stock air filter.
Will your X5s air intake nearly double as a result of installing an aftermarket system over a properly functioning stock air intake system? No, the intake track will only flow as much air as the motor needs, you will not be forcing air into the motor after installation of an aftermarket intake.
Will the X5 run lean as a result of a properly installed aftermarket air intake system? No, the air will still be properly metered by the vehicle allowing for a proper air to fuel ratio.
Will the X5s power be double? I wish, you'll noticed a blissful induction sound from the intake, the motor will be more responsive as it can breath better, and you'll pick up a little extra power thanks to the design of most quality aftermarket systems.
