About the RPI Scoops for the BMW E60 535i
The BMW E60 530i RPI ram induction for the 535i allows more ambient airflow to reach the stock air box. The stock airbox is a great foundation for intake modification because it allows the N54 engine to breath cool air from the outside unlike aftermarket induction systems. Other aftermarket intake systems rely on questionable testing methods (hood open) and suffer from heat soak which causes the BMW DME to pull ignition timing. Expect a 5-7hp gain with ram induction.
The BMC Filters are no longer available for purchase as it has been determined that it does not provide any HP gain.
