aFe Momentum ST Cold Air Intake - BMW X5 M (F85) / X6 M (F86) - 4.4L Twin Turbo S63
The aFe Momentum ST Cold Air Intake replaces the factory intake on the F85 X5 M and F86 X6 M with the 4.4L twin-turbo S63 V8. Two 279mm (11in) tall, 360-degree radial flow filters sit in a single sealed housing with a large built-in air scoop, and dyno-tuned XLPE tubes deliver the air to each turbo.
The one-piece housing is moulded from heat-resistant XLPE and uses aFe's filter-to-housing interface to keep the part count down. Slots in the housing send extra air towards the turbochargers and add to the induction sound. aFe's dyno testing shows up to +13 kW (+18 hp) and +27 Nm with Pro 5R filters, and up to +12 kW (+16 hp) and +24 Nm with Pro DRY S.
Options: Pro DRY S uses dry, oil-free three-layer synthetic media that washes clean with no oiling, suited to street and light off-road use; it flows 27% more than stock (865 CFM). Pro 5R uses pre-oiled five-layer cotton gauze media for the most airflow, washable and reusable; it flows 36% more than stock (925 CFM).
Note: Suits the F85 X5 M and F86 X6 M with the 4.4L twin-turbo S63 V8. Installation by a professional is recommended.
