About the RPI Scoops for BMW E63 6 Series 645i
The BMW E63 6 series 645i RPi's Ram Air Scoops converts your factory intake system into a ram air type. Other aftermarket induction kits mostly suck in hot air causing a loss of performance. The use of heatshields are not very affective as heat shields mainly work to block radiant heat. Utilizing the stock intake boxes, expect a 5 - 10 whp gain with 70mph airflow. RPi's Ram Air systems come with a 30-day money back guarantee. All kits come with a high flow BMC filter.
About the BMW Performance Air Filter for BMW E63 6 Series 645i (Optional)BMC air filters are designed and produced to ensure a higher air flow than original paper filters. In F1, for example, BMC cotton filters minimize the loss of air flow pressure passing through the air filter; this way ensures the best conditions for full exploitation of maximum power. Therefore the benefits of replacing the original paper filter with BMC cotton air filter, produced using the same technology and materials as the F1 air filters, are evident.
