（For）BMW OEM air ducts are "passive," meaning they require a vacuum to pull fresh air from the vents to the filters. If your OEM box is in tack, air scoops won't do much for your car as the vacuum is strong enough to feed the filters fresh air. If you decided to remove your OEM box then upgrade to BMS or other open air intakes, the "passive" air ducts won't feed the filters any fresh air (no vacuum). Adding the scoops with after market intakes will reduce the chance of heat soak and improve performance.

In order to convert the OEM air ducts from passive to active, air scoops are required (re-direct the incoming air by 90 degrees).

Features:

• Aircraft-grade Aluminum-Made of lightweight powder-coated aluminum for strength and styling. Don't choose plastic or stamped air intake scoops, they can easily melt from the heat or smell bad.
• Better Throttle Response-Aluminum heat shield that blocks heat and directs cool air to the filter
